Hi there! I understand you're having trouble getting the Avira Password Manager to open using Face ID. That must be concerning, especially when you're relying on it for quick access to your passwords. Let’s work through this together!

First, let's check a few things:

1. Ensure Face ID is Enabled for Avira: Go to your device's Settings, then scroll down to Avira Password Manager. Under this setting, make sure Face ID is enabled. If it appears to be enabled, try toggling it off and then back on.

2. Restart The App: Force close the Avira Password Manager app and then reopen it. To do this, swipe up from the bottom of the screen (or double click the Home button) to see the app switcher, find the Avira app, and swipe it off the top of the screen.

3. Check for Update: Ensure you have the latest version of the Avira Password Manager installed. Go to the App Store, tap on your profile photo, and scroll down to see if an update is available for the app.

4. Face ID Setup: Ensure that Face ID itself works well by testing it in other apps that use Face ID, like your banking app or another secure app. If Face ID is misbehaving across multiple apps, you might need to reset it in Settings > Face ID & Passcode and set it up again.

5. Reinstall the App: If all else fails, consider uninstalling and then reinstalling the Avira Password Manager. This can often resolve underlying issues.

If none of these steps resolve the issue, sometimes a problem with app permissions on newer iOS versions can interfere. If that's the case, you may need to dive deeper into the app's permissions or even reach out to Avira support directly at [email protected].

Let me know how it goes! Are you satisfied with the solution I provided?
