Bitwarden

Proton is safer from enshittification imo, it's not as open source (backend is closed), but it's their lack of VC funding and the majority owner or the company being the Proton Foundation non-profit that reassures me. They also have an history of lowering their prices if they come down, like with Pass. Other than that I think 1password is also very good in terms of security, though not open source

The fact is, both are still probably less open source compared to BW, but at least they don't use open source as a marketing point
