Passkey login fails in PayPal app on iOS

[keepassium]

Reported on Reddit:

The PayPal record in my database has an existing passkey, but it appears that logging into the PayPal app with KeePassium and that passkey is not currently working. I also have a PayPal passkey saved in ProtonPass, and when ProtonPass is set as the iOS password manager, just navigating to the PayPal app login screen auto prompts for logging in with the PayPal passkey in ProtonPass. If I ignore that auto prompt and enter my e-mail and then choose the passkey login option, it again pops up the ProtonPass passkey login prompt.

None of these things happen however, when KeePassium is set as the iOS password manager. Navigating to the PayPal app login screen does not auto prompt for logging in with the PayPal passkey in KeePassium. If I enter my e-mail address and then choose the passkey login option, again nothing happens.

Environment:

• OS: 18.2.1
• App Version: 2.1
• PayPal app version: 8.76.0
