iOS: "Save Password with biometric key store" fails

[abawany]

Describe the bug
Since the latest update on iOS 16.x, I am seeing the following problem: when a local file is opened and its password specified, if the Save Password with biometric key store box is checked, the following error is generated:

Unknown error while trying to open file. PlatformException(SecurityError, Err while writing data: -25293: The user name or passphrase you entered is not correct., null, null)

Unchecking the above box allows the file to be opened as normal but one must then re-select the file and re-enter the file password at a later date. Previously, with the box checked, this worked fine and also allowed subsequent accesses to this file after entering the phone PIN.

To Reproduce
Steps to reproduce the behavior:

1. Start AuthPass on iOS
2. Open local file and using the file picker, select the kdbx file of interest
3. Enter the kdbx access password and ensure the Save Password with biometric key store checkbox is checked
4. The above error occurs

Expected behavior
Versions prior to this allowed the file to open. Subsequent/later accesses to the file were managed by the phone PIN.

Smartphone (please complete the following information):

• Device: iPhone 13
• OS: iOS 16.x
• Browser: n/a
• Version: 1.9.9+1975

I also tried the recipe mentioned here: https://forum.authpass.app/t/error-while-error-retrieving-item-25291-25291-no-keychain-is-available-you-may-need-to-restart-your-computer/103 but noticed no subsequent change in behavior.

It looks like this bug in biometric_storage is probably the reason? authpass/biometric_storage#101

I also used the app with the option "Save Password with biometric key store?" checked true. However I do not actually use any biometric authentication. The App would just prompt me to enter my phone PIN to open the file, which worked fine, until the mentioned update. Now I can also only open a file when I uncheck the mentioned option and enter the keystore master password every time.

So while this is certainly an issue:

It looks like this bug in biometric_storage is probably the reason? authpass/biometric_storage#101

for my case (just PIN) the error probably resides in a different place.
