I think it depends on the mobile device you use. I've read that proton is better on iPhone and bitwarden doesn't integrate that well with it but it's seamless on android. I also haven't had any issues with bitwarden and Firefox and they've been my combo since I started using bitwarden a couple years ago. I haven't given proton pass a full on try yet though and I pay both companies for their awesome services so I'm a bit of a shill for both. I don't think you can make a bad choice here.

I have both. Had Bitwarden for many years but trying out Protonpass as an alternative. Bitwarden still the one for me at this moment

Recently found Bitwarden from a Lemmy recommendation. I have been very satisfied thus far.

Integrates with Safari & Arc on MacOS, Edge & Chrome on work PC, & Safari on iPhone and iPad.

I subscribe and Proton Pass will generate email alias forward to your protonmail account. It is fantastic. Now to clean up all the accounts I used under bitwarden

I have all things in Proton except password manager. I'm already using Bitwarden, and I don't think keeping all your eggs in one basket is a good idea. That and I don't want to support it, as Proton should be focusing on improving their existing products instead of creating new ones.

I love bitwarden. I don't use Firefox though. Any password manager you hold the keys on is good though. Used a few years now

Just started trying to use bitwarden since the LastPass breach, and importing has been a nightmare

Can't seem to get lastpass export to work.
