Recently this app has stopped working in Incognito despite the setting allowing it to.

v1.56.6 stopped working in for me in FF dev edition 98.0b9 (64-bits) on Win10. Never had issues before, but I can't log in and just see a spinner. Reinstalling did not help, downgrading to the previous version fixed the issue.

When not logged in, it keeps asking for saving credentials for sites. When choosing never to save, it will ask the same question again. Only way to stop this is by logging in. Even though I click "Never for this website", it won't remember my selection for certain sites. The second: The auto-fill feature doesn't work properly on certain sites and it's an annoying process to disable it.

Quasiment parfait !
Il manque, à l'image d'autre service du genre, une icône cliquable à côté des inputs afin d'accéder plus rapidement à nos informations de connexion.
De plus les thèmes ne sont vraiment pas terribles..

With the latest version 1.56.6. It keeps locking with every browser restart. When I got the Vault timeout set to "Never". So I downgraded to 1.55.0 and it worked. Never locking on browser restarts.

Really nice extension. It works like a charm.
However, 2FA using Yubikey could be improved. Currently it's checked only once. It could be nice to force 2FA every month for instance or less.
