Bitwarden is bolstering user account security for logins from unrecognized devices. Learn more about what triggers the new verification process and who is affected.

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.
