I've been using it for quite some time now (6 months+). I moved from 1Password to Proton suite. Proton Pass works just fine. it lacks the many options I've had in 1Pass, but honestly, barely used more than 2-3 categories.

So far, I've found only 2 websites that create a bit of an issue, by not allowing the login credentials to auto-populate.

Using the Unlimited (paid) version, totally worth it
