How to enable Biometric Login on Trust Wallet? (FaceID/Fingerprint)

Accessing Security Settings

1. Open the Trust Wallet application on your mobile device.

2. Tap the profile icon located in the top-right corner of the home screen.
3. Select Security & Privacy from the dropdown menu.
4. Scroll down to locate the Biometric Authentication toggle.
5. Tap the toggle to activate biometric login for wallet access.

Device Compatibility Requirements

1. Face ID support is available only on iPhone X and newer models running iOS 12 or higher.

2. Fingerprint authentication works on Android devices equipped with a functional fingerprint sensor and Android 6.0 (Marshmallow) or later.
3. The device must have biometric features enabled at the system level before Trust Wallet can utilize them.
4. Some custom Android skins may restrict third-party app access to biometric APIs unless explicitly permitted in device settings.
5. Jailbroken or rooted devices will not allow biometric login due to Trust Wallet’s built-in security restrictions.

Enabling Biometric Prompt for Transactions

1. After enabling biometric login, go back to Security & Privacy.

2. Locate the option labeled Require Biometrics for Transactions.
3. Toggle it on to enforce fingerprint or face verification before every transaction confirmation.
4. This setting applies to all supported blockchain networks within the wallet, including Ethereum, BSC, Polygon, and Solana.
5. If disabled, only the initial wallet unlock requires biometrics while transaction signing uses the standard password or PIN fallback.

Recovery and Fallback Mechanisms

1. Trust Wallet does not store biometric data — all verification occurs locally on the device using native OS frameworks.

2. If biometric sensors fail or become unavailable, users can fall back to their wallet password or recovery phrase.
3. Disabling biometrics in device settings automatically disables the feature in Trust Wallet without requiring re-authentication.
4. Resetting device biometric credentials triggers an immediate deactivation inside the wallet until manually re-enabled.
5. Users retain full control over when and how biometrics are used — no remote activation or forced enrollment exists.

Frequently Asked Questions

Q: Does enabling biometric login expose my private keys to Apple or Google servers?A: No. Private keys remain encrypted and stored exclusively on the device. Biometric data never leaves the hardware secure enclave or trusted execution environment.

Q: Can I use biometric login on multiple Trust Wallet installations across different devices?A: Yes, but each installation must be configured separately. Biometric settings are not synced between devices or cloud backups.

Q: What happens if I delete and reinstall Trust Wallet?A: All biometric preferences are erased during uninstallation. You must restore your wallet using the 12-word recovery phrase and re-enable biometrics manually.

Q: Is biometric login supported for hardware wallet connections like Ledger or Trezor?A: No. Biometric authentication applies only to software wallet access and transaction confirmations. Hardware wallet interactions follow their own physical verification protocols.
