Overall it's fast, ergonomic and works without getting in the way. Some arbitrary limitations if you don't have the ultimate subscription but nothing dealbreaking.

I find this extension very useful, but still somewhat lacking in my particular use case.

I share web site passwords among several browsers, and don't feel comfortable giving each of them (or even: any of them) full access to all the vaults. A compromise in one browser or any of its extensions shouldn't risk to expose high value assets like credit cards or infrastructure level passwords. Yet it doesn't seem possible to restrict access (I have a Proton Unlimited subscription) to one particular vault.

I worked around this by creating an additional free account solely to manage these less critical passwords: one can't compromise what's not even there. I'm not even sure whether this procedure is acceptable use, I didn't find anything against it but then I didn't look very hard.

I also noticed that access tokens have been introduced recently, so maybe features like this are on the roadmap somewhere.

Switched to Proton Pass from Bitwarden after it got worse. Proton Pass has great features and this add-on works well consistently in my browser. Easy to use, great features, good encryption. The new password management standard.

Works smoothly, without any issues

Excellent, but very worrying. The extensions, I don't know if due to updates or something else, lose their blocking configuration and suddenly have open access. This is recurring, in several browsers I use, it's not a specific issue, or the browser, or whatever.

Excelente, mas muito preocupante. As extensões, não sei se por atualizações ou por nada, perdem a configuração de bloqueio e ficam com acesso livre, de repente. Isso é recorrente, em vários browsers que utilizo, não é questão pontual, ou do browser, ou sei lá.

This app is really good one. I never used password managers before. I use it because i really trust Proton!
Thanks you a lot!
