For the most basic of password management needs, Proton Pass [in its current state] is OK, but it is nearly a decade behind, which is obvious.
Compared to how Bitwarden matches by base domain, host, regular expression, etc., Proton Pass may as well be unusable (uses a simple search, so having a frequently used email of @domain.com and then having a domain.com website to log into means you get hundreds of "matching" credentials.)
UI is not compact, at all--very inefficient UI.
