Bitwarden users who store their email account credentials within their Bitwarden vaults would have trouble accessing the sent codes if they are unable to log in to their email.
To prevent getting locked out of your vault, be sure you can access the email associated with your Bitwarden account so you can access the emailed codes, or turn on any form of two-step login to not be subject to this process altogether.
We already covered this at the top. You keep the recovery codes unexposed to the internet or obfuscated in some way, unlike your usual password. Therefore you can have confidence that they haven’t been hacked, leaked, or whatever like passwords often are.
anyway I tire of your sea lioning. if you are truly asking good faith questions you can research on your own from here.
How is a strong password I used exclusively for Bitwarden “exposed to the internet”? I do see the value of this for people that don’t care about security and reuse the same password everywhere. In that case you would need something like phishing to expose the 2FA code or the recovery code, just a leak of the email-password combination from another website would not be enough. But what’s the point if I’m already using a unique strong password specifically for Bitwarden?
