Proton Pass ranks #3 of 9 in our password managers testing. open-source clients under gplv3, a fresh 2026 audit, and a server you still have to take on faith..
86/100
a genuinely recent independent audit and copyleft clients put it third — the closed server is what keeps it from competing with the two above.
why people look for an alternative
−server is closed source
−free tier permits no vault sharing at all
−pricing page renders client-side; figures not vendor-page confirmed
−no self-hosting option
stay with Proton Pass if most recent independent audit here — recurity labs, early 2026 is the thing you care about most — nothing below beats it on that.
#2 in password managers · free, fully open, and the only one with no server at all — there is no vendor vault for anyone to steal.
89/100
verdictstructurally immune to the incident that defines this category, at the cost of doing your own syncing — a trade that is obviously right for some people and obviously wrong for others.

#4 in password managers · the best key architecture in the category, from the vendor that just made its audit reports harder to read.
84/100
verdictthe secret key design genuinely raises the floor on a weak master password — but a closed stack whose reports moved behind a request form in late 2025 is asking for more trust than it used to.
