Hello,

We recommend uninstalling and reinstalling the application to get started (don’t worry, you won’t lose any data: https://bitwarden.com/help/product-faqs/#q-does-uninstalling-or-deleting-my-bitwarden-app-also-delete-my-vault-data).

After that, follow these steps and let me know the results:

1. Open Finder.
2. Press Shift + ⌘ + G
3. Enter ~/Library/Application Support/Mozilla in the box that appears.
4. Is there a folder named NativeMessagingHosts inside the Mozilla folder? If not, right click, select “New folder” and title it NativeMessagingHosts (it has to be exactly how it is typed here, with the caps and no spaces).
5. Close your Firefox browser.
6. Open the Bitwarden desktop app.
7. Check off the option Enable Browser Integration then back on, and make sure the option Unlock with Touch ID is checked as well.
8. Launch Firefox (ensure in the browser extension Unlock with biometrics is checked also).

If the previous steps don't solve your issue, you'll want to make sure that the “Native Messaging” permission is enabled. It is an optional permission; however, it is required to function on Firefox:

Hi Thanks for the fast response and the checklist. I checked everything and it doesn't resolve my problem which is persistent since the last desktop app update from app store. Also I removed the entries from the OSX keychain (Bitwarden_biometric and others).

Now I enabled the logs (https://bitwarden.com/help/product-faqs/#q-how-do-i-get-logs-for-the-desktop-app) I see a lot of errors listed below.

13:32:50.864 › Error: Das angegebene Objekt konnte nicht im Schlüsselbund gefunden werden.
13:32:50.920 › Error: Das angegebene Objekt konnte nicht im Schlüsselbund gefunden werden.
13:33:07.204 › Error: Das angegebene Objekt konnte nicht im Schlüsselbund gefunden werden.
13:33:09.148 › Error: Das angegebene Objekt konnte nicht im Schlüsselbund gefunden werden.
13:33:09.150 › Error: Das angegebene Objekt konnte nicht im Schlüsselbund gefunden werden.
13:33:09.169 › Error: Das angegebene Objekt konnte nicht im Schlüsselbund gefunden werden.

Translated to english it would be like this: Error: The specified item could not be found in the keychain

Also this log entry will be created as soon I used biometric in the chrome/firefox app the command invalidateEncryption will throw my error message:

received event of :  message {
  appId: 'aaaa-aaaa-aaaa-aaa-aaaaaaaaaa',
  message: {
    encryptedString: '2.V3HbPWtIzea......2JUg=',
    encryptionType: 2,
    data: 'QzX0.......FidT7Iz/vg==',
    iv: 'V3Hb.....7EQ==',
    mac: '8QsX....212JUg='
  }
}
dispatching event to socket  :  message {
  command: 'invalidateEncryption',
  appId: 'aaaa-aaaa-aaaa-aaa-aaaaaaaaaa'
}

Hopefully this helps to find out what could be the problem...

Having same issue i reinstalled and still doesn't work. when i go to bitwarden on desktop and use my windows hello to unlock i can then use biometrics in browser. Before i could use the biometrics whether i logged in to bitwarden desktop or not.
