Password Manager for clients

I know Keeper and Bitwarden are popular here . I would be interested more in something that is only msp and not direct but I am open to other options if it’s a better product. One of our client is asking for one with a Vault to reduce manual entry but I am concerned about putting all eggs in one basket. At the same time I understand the alternative of saving the passwords in an Excel and putting it on the desktop :-) .

For those of you who use My Glue , can the client end users use it as a password manager similar to Keeper and Bitwarden ?
