How to set up biometric authentication on Trust Wallet?

Enabling Biometric Authentication in Trust Wallet

1. Open the Trust Wallet application on your mobile device and ensure you are logged into your wallet.

2. Tap the profile icon located in the top-right corner of the main screen to access settings.

3. Navigate to Security Settings and select Biometric Authentication.

4. Toggle the switch to activate biometric login, then confirm your fingerprint or face ID when prompted by the system.

5. Once enabled, the app will require biometric verification each time it is launched or when accessing sensitive features like sending assets.

Device Compatibility Requirements

1. iOS users must be running iOS 12 or later and have Face ID or Touch ID configured at the system level.

2. Android devices require Android 6.0 (Marshmallow) or higher with a supported fingerprint sensor or facial recognition module.

3. The device must have biometric hardware activated and registered through its native settings before Trust Wallet can utilize it.

4. Some custom Android skins may restrict third-party app access to biometric APIs unless explicitly granted in device permissions.

5. Devices without certified secure enclaves may display warnings or limit biometric functionality for security reasons.

Recovery Options When Biometrics Fail

1. A backup password or PIN remains active even when biometric authentication is enabled and serves as the fallback method.

2. If multiple failed biometric attempts occur, Trust Wallet may temporarily lock biometric access and prompt for the recovery phrase or password.

3. Users can disable biometric authentication entirely via Security Settings using their existing wallet password.

4. In cases where device biometrics are reset—such as after a factory reset—the Trust Wallet biometric toggle must be re-enabled manually post-reinstallation.

5. Loss of device biometric data does not affect wallet seed phrases; all private keys remain secured locally and recoverable via the 12-word mnemonic.

Security Implications of Biometric Use

1. Trust Wallet does not store biometric templates; verification occurs entirely within the device’s secure hardware environment.

2. Private keys never leave the device nor get exposed during biometric validation, preserving cryptographic integrity.

3. Enabling biometrics does not alter how transactions are signed—signing still happens locally using the wallet’s internal key management system.

4. Malware targeting clipboard or overlay attacks remains possible regardless of biometric status, so users should avoid suspicious apps and phishing links.

5. Biometric authentication only protects app entry and certain UI actions—not network-level threats or smart contract vulnerabilities on connected dApps.

Frequently Asked Questions

Q: Can I use biometric authentication on multiple devices with the same Trust Wallet account?A: No. Each Trust Wallet installation is isolated. Biometric enrollment is tied to the specific device and cannot be synced across devices.

Q: Does enabling biometrics mean my private keys are stored in the cloud?A: No. Trust Wallet never uploads or stores private keys anywhere outside the user’s device, regardless of authentication method.

Q: What happens if I delete my fingerprint from the phone settings?A: Trust Wallet will no longer recognize the biometric input and will require your wallet password or recovery phrase to regain access.

Q: Is biometric authentication mandatory after updating Trust Wallet?A: No. It remains an optional setting. Users retain full control over whether to enable or disable it at any time.
