Former 1password user, current Bitwarden user. Jumped ship when 1password dicked local vaults. Never been happier.

And it’s a FUCKLOAD cheaper. 1password is very overpriced.

Bitwarden has integration with Fastmail, as well as for many other alias services (anon addy, SimpleLogin, etc). They also just added support for selfhosted anon addy, and are working on adding support for self hosted SimpleLogin.
