Purpose

The Biometric Lock feature in Tonkeeper serves as a critical layer of local security for your non-custodial wallet. Its primary purpose is to gate-keep access to your funds and sensitive actions (like viewing your recovery phrase or signing a swap) using your unique biological data. In 2026, where mobile devices are the primary gateway to Web3, biometrics ensure that even if your phone is unlocked or physically stolen, an unauthorized user cannot execute transactions or drain your Toncoin without your physical presence. This feature bridges the gap between high-level blockchain security and seamless, everyday usability.

Step-by-Step

1. Access the Settings Menu

Open your Tonkeeper app. Locate the Settings icon (the gear symbol), usually found in the top-right or bottom-right corner of the main dashboard depending on your OS version.

2. Navigate to Security & Privacy

Scroll down the settings list until you find the "Security" or "Privacy and Security" section. Tap it to view your current protection methods.

3. Define Your Passcode First

If you haven't already, the app will require you to set a 4 or 6-digit PIN. This acts as a backup in case the biometric hardware fails or your face/finger is not recognized.

4. Toggle Biometric Authentication

Look for the switch labeled "FaceID" (iOS) or "Biometric Authentication / Fingerprint" (Android). Toggle this switch to the ON position. Your phone will prompt you to perform a scan immediately to verify ownership.

5. Set Authentication Frequency

In the same menu, look for "Lock Timeout" or "Require Authentication." For maximum security in 2026, set this to "Immediately" so the app locks every time you minimize it or switch to a different screen.

Use Case

The Public Commuter:

A user is checking their portfolio on a crowded train. If a thief "shoulder surfs" their PIN code and then steals the phone, they still cannot access the wallet because Tonkeeper will demand a FaceID scan for any outgoing transaction. The biometrics act as a final barrier that a PIN observer cannot bypass.

The DeFi Power User:

A trader is performing multiple swaps on a DEX. Instead of typing a complex 6-digit code for every single transaction—which is prone to errors and fatigue—they simply use their Fingerprint. This makes the Web3 experience feel as fast and intuitive as a traditional banking app while maintaining superior security.

Best Results

For the best results in 2026, ensure that "Sign Transactions with Biometrics" is enabled separately if your version of Tonkeeper offers it. This ensures that even if the app is open, no money can leave the wallet without a biological scan. Additionally, keep your device's OS updated to the latest version to ensure you have the most recent security patches for the Secure Enclave (iOS) or Trusted Execution Environment (Android). If you are using Tonkeeper Pro, consider using biometrics for daily small trades but requiring a manual "Multi-sig" approval for larger amounts over a certain threshold.

FAQ

Does Tonkeeper store my fingerprint or face data?

No. Tonkeeper uses the system-level API provided by Apple or Google. The app only receives a "Yes" or "No" from your phone's secure hardware. Your biological data never leaves the device and is never uploaded to the blockchain.

What happens if my biometric scanner breaks?

You can always fall back to the PIN code you created during the initial setup. If you forget both, you will need to use your 24-word recovery phrase to reinstall the wallet and reset your security settings.

Can I use FaceID on Tonkeeper Desktop?

In 2026, Tonkeeper for macOS supports TouchID. For Windows users, Windows Hello (Face or Fingerprint) is supported on compatible hardware through the Tonkeeper Pro desktop application.

Disclaimer

Biometric security is highly effective but not infallible; high-quality 3D masks or sophisticated spoofing can occasionally bypass older sensors. Biometric locks protect the local access to your app but do not protect your funds if your 24-word recovery phrase is stolen. Always keep your seed phrase offline and on paper. This tutorial reflects the biometric integration standards as of early 2026.
