WHAT: BW server can rotate a/group of passwords and email user new password.
WHY : This will help organization to implement regular password rotation policy.
The Bitwarden server can’t do this since it does not have your vault’s encryption key. You would have to allow the server to store your encryption keys which is a violation of the zero-knowledge architecture that Bitwarden operates.
Maybe the clients could implement this and sync between to agree on a date and an operator (which client generates the news password) ? The client would need to be unlocked and thus have access to the vault.
