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.
I can’t believe people are arguing about and downvoting this. Especially for a service that holds all of your passwords, it’s the highest priority thing for you to secure.
Never underestimate the human capacity for short-sighted laziness.
