MetaMask Signature Request Not Working? Fix It (2026)

By Qbitics Editorial

A MetaMask signature request not working can prevent you from signing in to decentralized applications (dApps), verifying wallet ownership, accessing NFT marketplaces, or completing certain cryptocurrency operations.

Sometimes the signature window never appears. In other cases, you click Sign, but the website continues loading or displays an error such as "User rejected the request" or "Signature verification failed."

The problem may involve a browser extension conflict, an incorrect wallet account, an expired authentication message, a disconnected dApp, or a signing request that your wallet does not support.

According to MetaMask's official documentation, digital signatures allow users to prove control of their wallet accounts. However, signing a message is different from submitting a blockchain transaction, and some signatures can authorize sensitive actions.

This guide explains why MetaMask signature requests fail, how to troubleshoot missing signing prompts, and how to recognize potentially dangerous requests before approving them.

Why Is My MetaMask Signature Request Not Working?

MetaMask allows websites and decentralized applications to request digital signatures for authentication and other purposes.

When a dApp requests a signature, MetaMask normally displays a confirmation interface where you can review the request and decide whether to sign it.

If the process fails, possible reasons include:

• Signature window not appearing: The browser or wallet has not displayed the request.
• Incorrect MetaMask account: The connected account differs from the account expected by the application.
• Expired authentication request: The message or sign-in challenge is no longer valid.
• Rejected request: The user or wallet refused the signature.
• Browser wallet conflicts: Another wallet extension may interfere with MetaMask.
• Application connection issue: The dApp cannot communicate correctly with the wallet.
• Unsupported signing method: The account or application does not support the requested signature format.
• Security warning: MetaMask identifies potential risks associated with the request.
• Hardware wallet issue: A connected hardware device cannot complete the signing operation.

The appropriate solution depends on whether MetaMask never received the request, the signature was rejected, or the application failed to verify a successfully generated signature.

MetaMask Signature Request Errors: Quick Fix Table

How to Fix MetaMask Signature Request Not Working

Before approving another request, confirm that the website is legitimate and that you understand what you are signing.

Step 1: Check Whether MetaMask Has an Open Request

Sometimes a decentralized application submits a request, but the MetaMask window is hidden behind another browser window.

Open the MetaMask extension manually.

Check whether a signature confirmation request is waiting for your decision.

If a request exists, inspect the originating website and message.

Do not approve an unexpected request simply to make an error disappear.

If no request appears, return to the legitimate application and check whether the original request has expired.

Step 2: Confirm the Correct MetaMask Account

A signature is associated with the account used to generate it.

For example, a website may expect a signature from Account 1 while MetaMask is currently using Account 2.

The application may reject the signature because it does not match the connected address.

To troubleshoot:

1. Open MetaMask.
2. Check the selected account.
3. Compare its public address with the account shown by the dApp.
4. Switch to the intended account if necessary.
5. Request a fresh signature.

Never disclose your private key or Secret Recovery Phrase to prove account ownership.

Step 3: Refresh the Decentralized Application

A temporary website issue may prevent the application from receiving or processing the signed message.

If you trust the website, refresh the page and start the authentication process again.

Review the new signature request carefully.

Do not assume that repeated requests are identical. The message contents, expiration time, or requested permissions may change.

Step 4: Restart MetaMask

MetaMask's official troubleshooting guide recommends restarting the browser or mobile application when the wallet stops working as expected.

For MetaMask Extension, close and reopen the browser.

For MetaMask Mobile, fully close and reopen the app.

Unlock the wallet and return to the legitimate website.

Try the signing process again after verifying the request details.

Step 5: Update MetaMask

Outdated wallet software may cause compatibility or interface problems.

Check for updates through your browser's official extension store or the appropriate mobile application store.

Install the current supported version.

Avoid downloading wallet updates from third-party websites or unsolicited messages.

Step 6: Check for Wallet Extension Conflicts

MetaMask warns that having multiple active browser wallets can interfere with dApp connections.

For example, a website may communicate with another installed wallet instead of MetaMask.

Check your browser's extension manager.

If several wallet extensions are active, investigate whether the application is selecting the intended provider.

Temporarily disabling conflicting extensions may help, provided you understand the effect on your browser.

Then reload the legitimate dApp and reconnect MetaMask.

Step 7: Contact the Correct Support Team

If MetaMask receives the request but cannot generate a signature, consult MetaMask Support.

If MetaMask signs successfully but the website rejects the result, the problem may be specific to that application.

Contact the dApp's official support team with the displayed error and non-sensitive technical details.

Do not share passwords, recovery phrases, private keys, or sensitive authentication messages.

MetaMask Signature Popup Not Showing

A missing signature popup is one of the most common wallet authentication problems.

You click Connect, Sign, or Verify Wallet on a website, but no MetaMask confirmation window appears.

This does not necessarily mean the blockchain network is unavailable.

Ordinary message signatures are usually generated locally and do not require an on-chain transaction.

How to Troubleshoot

First, open the MetaMask extension manually.

Check whether a request is waiting.

Next, return to the website and inspect the wallet connection status.

If the website is connected to another wallet, select MetaMask through its supported connection options.

You can also restart the browser and reload the application.

If the issue affects only one website, the site's wallet integration may be responsible.

Avoid repeatedly clicking Sign without checking whether earlier requests are still open.

MetaMask Sign Message Not Working

Some dApps ask users to sign messages to confirm account ownership.

These requests may be used for account login, wallet verification, or application-specific permissions.

According to MetaMask, signing a message uses the account's private key to create a cryptographic signature that another party can verify.

The private key itself is not shared with the website during a normal signing operation.

Why Message Signing Might Fail

Possible explanations include:

• The website sent an invalid or unsupported request.
• The requested account is unavailable.
• The wallet rejected the request.
• The authentication message expired.
• The dApp failed to process the signature.
• A connected hardware wallet does not support the requested operation.

How to Fix It

Confirm that MetaMask is connected to the correct website and account.

Review the actual message being presented.

If the request has expired, generate a fresh one through the legitimate application.

Restart MetaMask if the confirmation interface is not responding.

If the request continues failing, contact the application developer or support team.

Do not sign an unfamiliar hexadecimal message simply because the website claims it is required for verification.

MetaMask Sign-In With Ethereum Not Working

Sign-In With Ethereum, commonly called SIWE, allows users to authenticate with supported decentralized applications using an Ethereum account.

Instead of creating a traditional username and password, users sign a structured message that proves control of a blockchain address.

MetaMask officially supports Sign-In With Ethereum.

The underlying standard is EIP-4361.

Why SIWE Authentication Can Fail

A SIWE sign-in request may fail because:

• The signature was generated by the wrong account.
• The application issued an expired nonce.
• The authentication message uses an incorrect domain.
• The website session has expired.
• The signed message does not match the application's expected format.
• The application's backend cannot validate the signature.

How to Fix Sign-In With Ethereum

First, check that the website is legitimate.

Verify the address shown by MetaMask against the account expected by the application.

Review the domain, requested URI, and other available details in the signing prompt.

If the authentication request has expired, return to the website and generate a fresh request.

Sign only after confirming that the message matches the action you intended.

If the signing operation succeeds but the website continues displaying an error, the problem may involve its session or signature-verification implementation.

In that case, contact the application's support team.

MetaMask Signature Verification Failed

A "Signature verification failed" error generally means the receiving application could not validate the signature against its expected authentication requirements.

The exact explanation depends on the application.

For example, a website may expect a signed message containing a particular nonce, domain, or wallet address.

If any of those values differ from what the application expects, verification may fail.

How to Troubleshoot

Check that the connected wallet account has not changed.

Request a fresh authentication message.

Confirm that the website's domain and displayed message are correct.

Avoid copying an old signature into a new authentication session.

If the signature is produced successfully but the application repeatedly rejects it, ask the dApp's support team to investigate.

A failed signature verification is not necessarily a blockchain transaction failure.

MetaMask User Rejected the Request Error

Some applications display messages such as:

• User rejected the request
• User denied message signature
• Request rejected
• User denied transaction signature

These errors generally indicate that the wallet did not provide the requested authorization.

This can happen when you click Reject, close the request, or when the wallet or application cancels the operation.

How to Fix It

If you intentionally rejected the request, no action is necessary.

If you want to proceed, return to the legitimate dApp and initiate a new request.

Review the requested signature before approving it.

If the error appears without any visible MetaMask request, restart the wallet and check for application conflicts.

Do not repeatedly approve unfamiliar signing requests merely to bypass an error.

MetaMask Signature Request Keeps Appearing

Sometimes a website asks you to sign the same message repeatedly.

You approve the request, but the application returns to the login screen and asks for another signature.

This may indicate a session handling problem.

Possible causes include an expired authentication challenge, an incorrectly stored session, or a mismatch between the signed account and the account recognized by the website.

How to Fix Repeated Signature Requests

Check the connected account.

Refresh the application.

If the website provides a sign-out option, sign out and begin a fresh authentication session.

Review browser privacy or cookie restrictions if the site requires a browser session to maintain your login.

If the issue continues on only one website, contact its support team.

Repeated signing is not a reliable solution to broken authentication.

MetaMask Permissions Request Already Pending

The message "Permissions request already pending please wait" can appear when a decentralized application attempts to establish a wallet connection while a previous permission request remains unresolved.

MetaMask documents this issue in connection with decentralized exchanges.

Its recommended workaround is to disconnect the wallet from the affected website and then reconnect.

How to Fix It

Open the legitimate decentralized application.

Disconnect the wallet using its connection controls or MetaMask's connected-site management.

Return to the application.

Select Connect Wallet and choose MetaMask.

Review the new connection request.

If the connection succeeds, initiate the intended signing action.

Remember that disconnecting a website does not revoke existing on-chain token allowances.

MetaMask Signature Request Not Working on Mobile

MetaMask Mobile may encounter signing problems when interacting with websites through the wallet's browser or an external mobile browser.

The exact behavior depends on the device, application, and wallet connection method.

Troubleshooting Steps

1. Update MetaMask through the official application store.
2. Close and reopen the wallet.
3. Open the legitimate dApp through its supported mobile connection flow.
4. Verify that the correct account is selected.
5. Check whether a signing request is already open.
6. Generate a fresh request if the previous one expired.
7. Contact the dApp's official support team if the request continues failing.

Avoid reinstalling MetaMask as an initial troubleshooting step.

Reinstallation can create an account recovery problem if you do not have the information needed to restore your wallet.

MetaMask Signature Request Not Working With Ledger

Users who connect a Ledger hardware wallet through MetaMask may encounter additional signing problems.

MetaMask's official Ledger troubleshooting guide recommends checking device connectivity, firmware, browser compatibility, and the relevant Ethereum application.

How to Troubleshoot Ledger Signing

Make sure the Ledger device is unlocked and properly connected.

Open the relevant Ethereum application on the device.

Check whether Ledger Live is interfering with the connection.

Review the device firmware and application versions.

Some signing methods may require additional support or device settings.

Only enable advanced signing capabilities when you understand the risks and trust the application requesting the signature.

If the request remains unsupported, consult Ledger's official documentation and MetaMask's hardware wallet guidance.

Does Signing a Message in MetaMask Cost Gas?

Ordinary off-chain message signatures generally do not require a blockchain transaction.

Because they are generated locally without being submitted for blockchain execution, they usually do not incur network gas fees.

However, signing a message and executing a transaction are different operations.

A dApp may ask you to sign a message and later submit an on-chain transaction that requires gas.

Some signed permissions can also be used by another party to execute authorized actions later.

Therefore, the absence of a gas fee does not automatically make a signing request safe.

Is It Safe to Sign a Message in MetaMask?

Not every MetaMask signature request is harmless.

Legitimate dApps use signatures for authentication, order creation, and other activities.

However, malicious websites can ask users to sign messages that authorize dangerous operations.

MetaMask warns about signature phishing, where attackers trick users into signing off-chain messages that can later be used to transfer or control assets.

What to Check Before Signing

Website domain: Confirm that you are using the legitimate application rather than a lookalike website.

Message purpose: Understand why the application needs your signature.

Requested permissions: Check whether the message grants spending access or other authorization.

Token and amount: If the request involves cryptocurrency, inspect the applicable token and quantity.

Expiration: Review any deadline or validity period included in the request.

Security warnings: Pay attention to MetaMask's risk alerts.

MetaMask provides security alerts and transaction simulations, but these protections cannot detect every malicious request.

Never assume that a signature is safe simply because no gas fee is required.

What Is MetaMask Signature Phishing?

Signature phishing occurs when an attacker tricks a wallet user into signing a message that enables unauthorized activity.

Unlike traditional phishing, this attack does not necessarily require the victim to disclose a private key or recovery phrase.

Instead, the attacker persuades the user to approve a malicious request.

MetaMask identifies Permit2 signatures and malicious NFT permissions as examples of potentially dangerous signing mechanisms when abused.

A fraudulent application may present a request as an account verification or free reward claim when it actually creates an authorization that can be exploited later.

What If You Signed a Suspicious Message?

Stop interacting with the suspicious application.

Check the message contents and any associated permissions.

Review your wallet's token approvals and relevant signing authorizations through trusted security tools.

Where possible, revoke exposed permissions.

Be aware that revoking a conventional ERC-20 allowance does not necessarily invalidate every type of off-chain signature.

If you believe an attacker has ongoing access to your assets, seek official wallet security guidance and consider moving unaffected assets to a new secure wallet when appropriate.

Do not rely on strangers offering guaranteed cryptocurrency recovery.

MetaMask Signature vs. Token Approval vs. Transaction

These operations are related, but they should not be treated as interchangeable.

Some modern wallet permission systems combine steps or support sponsored transactions, so the exact fee and execution model can vary.

The most important distinction is whether you are authenticating, granting permission, or executing a blockchain action.

If your issue involves a conventional token allowance rather than message signing, read our related guide on MetaMask Token Approval Pending.

How to Prevent MetaMask Signature Errors

Several precautions can reduce signing problems and security risks.

Keep MetaMask Updated

Use the official application or browser extension and install supported updates.

Verify the Connected Account

Confirm that the account selected in MetaMask matches the address expected by the decentralized application.

Request Fresh Authentication Messages

If a signing challenge expires, create a new one through the legitimate website.

Avoid Conflicting Wallet Extensions

Check whether multiple browser wallet extensions interfere with the application's provider selection.

Review Every Signature

Do not approve a request just because it appears repeatedly.

Use Official Support Channels

Contact MetaMask or the affected decentralized application through verified support pages.

Protect Wallet Credentials

Never disclose your Secret Recovery Phrase or private keys to anyone offering to repair signature errors.

Frequently Asked Questions

Why Is My MetaMask Signature Request Not Working?

A MetaMask signature request may fail because of an incorrect wallet account, expired authentication message, browser extension conflict, application error, or unsupported signing method. Check whether the request appears in MetaMask and verify the connected account.

How Do I Fix MetaMask Sign Message Not Working?

Open MetaMask, check for a waiting signature prompt, verify the connected account, and request a fresh message from the legitimate application. Restart and update MetaMask if the signing interface is unresponsive.

Why Is My MetaMask Signature Popup Not Showing?

The signing window may be hidden, the dApp may not be connected correctly, or another wallet extension may be intercepting the request. Open MetaMask manually and check browser wallet conflicts.

What Does User Rejected the Request Mean?

It generally means the wallet did not provide the requested signature. This can happen when you reject or dismiss the request. If you intended to sign, initiate a new request and review it carefully.

Why Does MetaMask Keep Asking Me to Sign?

Repeated signing prompts may indicate an expired login challenge, account mismatch, session issue, or application error. Verify the website and account before retrying.

Does Signing a Message Cost ETH?

An ordinary off-chain message signature generally does not consume ETH because it does not require blockchain execution. However, a later transaction using the signed authorization may involve network fees.

Can Someone Steal My Crypto With a Signature?

Yes, certain malicious or misleading signatures can authorize dangerous actions without revealing your private key. Always inspect the request and avoid signing messages from untrusted websites.

Is Sign-In With Ethereum Safe?

Sign-In With Ethereum is a standardized authentication method supported by MetaMask. Its security depends on the website, message contents, and implementation. Verify the domain and details before signing.

Why Does Signature Verification Fail?

The application may be expecting a different wallet address, nonce, domain, or authentication message. Request a fresh challenge and confirm that the correct account is connected.

Can I Cancel a MetaMask Signature Request?

You can reject an unsigned request. Once a message has been signed, you cannot simply undo the cryptographic signature. Certain authorizations may need to be revoked, canceled, or allowed to expire according to their specific mechanism.

Should I Reset MetaMask to Fix Signing Errors?

No, not as an initial step. MetaMask recommends restarting, updating, and troubleshooting application connections before considering account resets or activity clearing. A wallet reset does not automatically invalidate previously signed messages.

Why Is MetaMask Not Signing With Ledger?

Hardware wallet signing may fail because of device connectivity, outdated firmware, application compatibility, or unsupported signing methods. Follow MetaMask and Ledger's official hardware wallet guidance.

Final Thoughts

A MetaMask signature request not working does not necessarily indicate a blockchain problem.

Many signing failures involve wallet connections, incorrect accounts, expired authentication challenges, or application-specific errors.

Start by checking whether MetaMask received the request. Verify the connected wallet account, inspect the message, and confirm that the website is legitimate.

If the signature is generated successfully but the application rejects it, the issue may involve the website's authentication system rather than MetaMask itself.

Most importantly, never approve a suspicious signature simply to bypass an error. Some off-chain signatures can grant sensitive permissions even when they do not require a gas fee.

By understanding the difference between message signing, token approvals, and blockchain transactions, you can troubleshoot signing issues without unnecessarily exposing your wallet.
