How to lock the android app with your fingerprint
Where: Settings › General settings › Security and Privacy

When to use it

Options
| Option | What it does | Default |
|---|---|---|
| Enable Finger Print Authentication | Asks for unlock when the app is opened. Applies to the whole app, not each account. | Off |
Good to know
- On Android 11 and later, your phone's PIN, pattern or password also works at the prompt. On Android 10 and earlier, a fingerprint is needed.
- The prompt appears when you open the app. It is not a timer that locks the app after you leave it.
- Secret Keeper has its own fingerprint setting.
Common questions
Why do I not see the option?
The row is hidden if your phone has no fingerprint or other biometric support.
What if I cancel the prompt?
The app shows Unlock cancelled and closes.
What if no fingerprint is enrolled on my phone?
The app says no fingerprint is enrolled, turns the setting off and opens normally. Enrol a fingerprint in your phone's settings and switch it on again.
