The whole point of a password manager is so you only have to remember one passphrase. Suggesting an actual sentence and not having byzantine passphrase requirements will help. My fiance is really bad with this one, I admit that I don't have much empathy here.
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.
Perhaps it has changed since, or maybe it was just hard to find. Oh well, too late now.
We ended up using 1Password. My only real complaint with it is the need to create a vault for sharing something from one user to another. That means that if any two people in the company want to share, they need to get an admin involved so the admin can create the vault.
