macOS: periodic prompting for touchID while running in the background

[jgoosens]

Description
I get prompted for touchID every X minutes (the interval does not seem constant). This is very intrusive as the little touchID prompt appears out of nowhere, receives focus from the OS and interferes with whatever you are doing at the moment. To be quite clear: This happens at random while doing nothing password-related, e.g. just while writing something in a text editor, browsing the web, etc.

How to reproduce
Not sure how to reproduce it. I've had this for a while now (also on the release prior to v1.54.156) and it persists across reboots. If any others encounter this issue, please comment that you're experiencing this problem as well under this issue.

Expected behavior
Keepassium should only prompt for touchID when trying to complete a password field or when opening the app after it has locked. No periodic prompts.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment:

• Device: MacBook Air M3,
• OS: macOS 15.3. The problem also occurred when i was still on 14.7.x (Can't remember the exact version I upgraded from)
• App Version: v1.54.156

My issue seem to be a potential duplicate of #237, but as that was closed with a build nr ref that contains a fix and I am still experiencing the issue, I decided to reopen the issue here.

Thank you for the feedback! This does indeed look similar to #237, but after two years probably deserves a new issue.

Can you tell me your app timeout setting? (Settings → App protection → Timeout)

[jgoosens]

AppLock is enabled and the app timeout is set to 5min.

The strange thing is that this popup does not appear deterministically every 5min, but the interval appears to be quite random.
