Bitwarden is end-to-end encrypted. So, password "resets" aren't really a thing without also resetting the vault as a whole.
Personally, I'm ecstatic that there is no recovery process to reset or recover a Bitwarden master password. No security questions. No email reset. No one-time use login codes (which would need to be stored somewhere not encrypted by a user's secret key in order to verify). Again, I can understand why an IT department would want that, but all that does is open up attack vectors that are very easy for an attacker to abuse.
The whole point of the master password is it's the ONE AND ONLY password you cannot forget or lose. One... lousy... password.
