How to enable Face ID or Biometrics in Trust Wallet? (App Access)

Understanding Biometric Authentication in Trust Wallet

1. Trust Wallet integrates device-level biometric systems to secure wallet access and transaction confirmations.

2. Face ID on iOS devices and fingerprint or face recognition on Android rely on the operating system’s native security framework, not Trust Wallet’s internal codebase.

3. The app reads the device’s biometric readiness status during launch and prompts users only if hardware and OS settings permit it.

4. Biometrics are never stored by Trust Wallet; they remain encrypted within the device’s Secure Enclave or Trusted Execution Environment.

5. Disabling biometrics in iOS Settings > Face ID & Passcode or Android Settings > Security > Biometrics will immediately prevent Trust Wallet from offering the option.

Enabling Biometrics During Initial Setup

1. Upon first opening Trust Wallet after installation, the app checks for available biometric sensors and displays a toggle labeled “Use Biometrics”.

2. Tapping “Enable” triggers the OS-native permission dialog requesting access to Face ID or fingerprint data.

3. If the user denies permission at this stage, Trust Wallet will not request it again unless biometric settings are manually re-enabled inside the app later.

4. A successful enrollment links the biometric gesture to the wallet’s local encryption key used for unlocking the app interface.

5. This step does not affect seed phrase storage or private key generation—those remain offline and unexposed to biometric subsystems.

Navigating Biometric Settings Within Trust Wallet

1. Open Trust Wallet and tap the profile icon in the top-right corner of the home screen.

2. Select “Security” from the menu to access authentication-related options.

3. Locate the “Biometric Authentication” toggle and switch it on if it is currently disabled.

4. The app will immediately invoke the OS-level biometric verification flow to confirm identity before activating the feature.

5. Once enabled, biometrics apply to both app launch and transaction signing unless overridden by individual transaction preferences.

Transaction-Level Biometric Confirmation

1. When initiating a swap, send, or bridge action, Trust Wallet displays a confirmation overlay before broadcasting.

2. If biometrics are active, this overlay includes a “Confirm with Face ID” or “Confirm with Fingerprint” button instead of a password field.

3. Users may disable biometric confirmation per transaction by tapping “Enter Password” beneath the biometric prompt.

4. Each confirmation uses a one-time cryptographic signature derived from the device’s secure hardware, ensuring no replay attacks are possible.

5. Failed biometric attempts trigger a brief cooldown period enforced by the OS—not by Trust Wallet—before allowing another try.

Frequently Asked Questions

Q: Does enabling Face ID mean my private keys are stored on Apple’s servers?No. Private keys never leave the device. Face ID only unlocks access to locally stored encrypted key material.

Q: Can I use Face ID on an iPhone without a passcode set?No. iOS requires a passcode to be configured before enabling Face ID. Trust Wallet enforces this dependency.

Q: Why does Trust Wallet ask for biometric permission again after updating?The app must re-request OS-level permissions following major updates due to iOS and Android security policies governing sensitive APIs.

Q: Will disabling biometrics delete my wallet or recovery phrase?No. Disabling biometrics only changes the unlock method. All wallet data remains intact and accessible via password or backup phrase.
