Hello, I come to suggest a quick solution to add Bitwarden account.
Account deletion cancellation without login.
Example: if my smartphone is stolen with the screen unlocked, the thief can delete my bitwarden account without login, just confirming the email via the link: Delete an Account or Organization | Bitwarden Help Center.
The thief will need to know which email is from the Bitwarden account, but his first attempt will be the one from the Gmail or Icloud mail app.
I suggest adding a time for the customer to be able to re-enter the account on another device and cancel this deletion request.
