Wrong passcode

After a wrong passcode the dots shake and Attempts left shows how many tries remain out of 5. After the fifth wrong passcode the keypad is locked for 5 minutes, and Disabled until shows when you can try again. After that you get one attempt; each further mistake locks the keypad for longer: 10, 15 and then 30 minutes. Closing or restarting the app doesn't reset the counter.

Attempts left: 4 — Wrong passcode: 4 attempts left.

Keypad disabled until a set time — Too many attempts: the keypad is locked.

Forgot the passcode? It can't be reset in the app. Delete the app and install it again, then sign in and, if needed, restore your wallets from their recovery phrases (see 3.5). Without the recovery phrases, wallets can't be restored.

Face ID and Touch IDFingerprint and face

Turn on the Face ID (or Touch ID)Biometrics switch in Security. From then on the lock screen opens the Face ID or Touch ID promptthe system Biometrics Scanner prompt by itself: touch the sensor or look at the camera, depending on what is set up on your phone. Cancel closes the prompt so you can enter the passcode. The button in the bottom-left corner of the keypadThe biometrics icon to the left of the bottom digit opens it again. After a wrong passcode, biometrics isn't offered until you enter the passcode correctly.

Biometrics works only together with the passcode. If there is no passcode yet, turning the switch on first opens Create Passcode with the text Set a passcode to enable Face IDSet a passcode to enable Biometrics. If you leave without saving a passcode, biometrics stays off — the switch turns back off.

If Android temporarily disables biometrics after several failed attempts, the app shows a Biometrics Scanner window with Enter passcode or try again later. Tap Passcode and enter your passcode.

Auto-Lock

Auto-Lock sets how long the app can stay in the background before it asks for the passcode again: Immediate, 1 minute (default), 5 minutes, 15 minutes, 30 minutes or 1 hour. The row appears only when a passcode is set.

Change or turn off the passcode

Change: tap Edit Passcode, enter the current passcode on the Unlock screen, then enter the new passcode twice.
Turn off: tap Disable Passcode and enter the current passcode. The passcode is removed at once, and biometrics is turned off too.
