Is it planned to implement passwordless authentication, which enables you to login via push notification on the mobile app?
This feature isn’t available for self-hosted (yet), not even the Bitwarden self-hosted. So it will not work for Vaultwarden either.
Also, it looks like it is tied to there notification/push channel, which Vaultwarden isn’t able to use either.
Until it isn’t available for self-hosted, we probably arn’t able to add this feature just yet.
