Recover accounts in your organisation

I set up an organisation for my family, now I have the problem that my brother seems to have lost his password to his bitwarden vault. Which is a bummer. But It would be great if I could help him to regain access to it again. I think that is a recurring thing in families, I set up bitwarden so that my family would use better passwords but they have no real interest in this topic at all. So I’m the one maintaining this. Not them.
