Why YSK: Because if you are like most people, you also store your email’s password in your Bitwarden Vault and not bother remembering it, causing you to potentially get locked out (since you wouldn’t be able to log in to your email to get the verification code, because your email’s password is in the vault itself 👀)
(Imagine leaving your key in your house, lol)

Excerpt:
To keep your account safe and secure, in February 2025, Bitwarden will require additional verification for users who do not use two-step login. After entering your Bitwarden master password, you will be prompted to enter a one-time verification code sent to your account email to complete the login process when logging in from a device you have not logged in to previously. For example, if you are logging in to a mobile app or a browser extension that you have used before, you will not receive this prompt.
Good thing I noticed, otherwise I might’ve had a bad time next month 😖
Edit: Updated title to clarify that people who have 2FA are not affected.
People are “hacked” all the time in massive breaches. Its accelerating, not getting less likely. Password managers are a huge target, and have been breached in the past.
If youre worried about it, use something like Aegis. Its an mfa app that lets you easily save password protected backups. You can set it up to automatically save a copy to a folder on your phone. Then just copy that file off and store it somewhere safe.
If thats too much work and you dont run syncthing/nextcloud/etc, they also have an option to let it it sync with the google backup service.
The above gives you the best of both worlds : strong security and strong redundancy.
