For training delivery, I have a separate account on my mac to help isolate what's available and reduce the chances for a mistake. The new "Must be signed in" 1Password either breaks the isolation (exposes all my passwords in the desktop boundary) or requires me to pay for extra users. Bitwarden requires me to get the app via the Mac app store, which means the app is associated with an apple account, again, reducing isolation.

What's the best standalone password manager that includes firefox integration?

@adamshostack Bitwarden doesn’t require Mac App Store, that is just the default option on Mac.

DMG file is available here: https://bitwarden.com/download/#downloads-desktop

Alternatively:
brew install bitwarden

@rjmd thanks! The page google brought me to (I think) didn't make that at all clear - but its in the other account so double checking is a pain :)
