How does biometric authentication work? How do I activate it?

You can use biometric authentication (fingerprint or facial recognition) instead of entering an access code and scanning your card to log in to the Tangem app, view your coin and token balances, switch between wallets if you have more than one.

To activate this biometric authentication, follow these steps:
1. Open the Tangem app.
2. Tap on the three dots in the top right corner of the screen.
3. Go to "App Settings".
4. Enable "Wallet saving" and "Access code saving".

When you enable "Wallet saving", all Tangem wallets (if there is more than one) will be linked to the app. You can now gain access to the app with biometric authentication. 

When you enable "Save access code", the access codes will be stored on your phone in encrypted form. When dealing with the cards, you'll have to use biometric authentication instead of an access code.
Important! To sign a transaction, you must still need your Tangem card.
