FWIW, I have set up many, many non-technical users on an enterprise 1Password account. To those who haven't used a password manager there is a really big learning curve and I've seen tons of struggling.
I think a lot of it is the separate "vaults" concept can be easy to fuck up. I've had multiple instances where users have accidentally saved individual credentials in a shared vault because they didn't realize they weren't saving to their private vault.
Perhaps it's just the enterprise use cases that can confuse people, I'm guessing if you're just using it as 1 person with a single private vault there are fewer issues.
Personally, I have no experience with lastpass. Just wanted to point out this anomaly.
