It is really nice that after years of having to manage 1Password user accounts on the web alone, the company is finally bringing family account management to the app itself. The feature is available now for macOS, Windows, Linux, and Android. It’s coming to iOS ‘later this week.’

I'm glad you got the family account discount. Let us know how it is and how you like it, after changing to family account.
