I guess you mean the desktop app? - Anyway… any version “2023.10.x” is completely outdated and you should update it (I guess, your Bitwarden browser extension is up-to-date?!).
Have you logged out of the desktop app and logged back in since making those changes? I was dealing with this recently and noticed when making some changes, need to log out and log back in on both the app and extension before the changes take place.
and if it still doesn’t work, it might be that you are affected by some current bugs around biometrics (there were some reports)… I’m not that into the details here… for Firefox and/or Windows there are definitely some current bugs…
that your MacOS desktop app is installed via the app store
Unfortunately, this may be my issue. Gener8 is not available on the app store, therefore I have side loaded it. I also found this note which further supports it. Understandably, not much can be done for now.
Biometric Unlock for Browser Extensions is available for only Chromium-based browsers (e.g. Chrome, Edge) with v1.48.0 of the Browser Extension, provided you have the latest version (2021-01-19) of the Desktop App.
When your Browser Extension updates to this version, you may be asked to accept a new permission for Bitwarden to Communicate with cooperating native applications. This permission is safe, but optional, and will enable the Browser Extension to communicate with the Bitwarden Desktop App, which is required to enable Biometric Unlock (see here for details). Declining this permission will allow you to use v1.48.0 without Biometric Unlock functionality.
Biometric Unlock is currently not available for:
Firefox Browser Extensions below version 87.
Microsoft App Store Desktop Apps (a side-loaded Windows Desktop App, available at bitwarden.com/download/ will work fine).
Side-loaded MacOS Desktop Apps (an App Store Desktop app will work fine).
