I recommend against this extension because the free version allows creating just one extra vault. It is not really possible to organize several notes in this way. It is abusive of users since it doesn't cost anything to allow extra vaults. At least five vaults should have been allowed for free users. Meanwhile, I have no choice but to stick to Bitwarden which has no such limitation.

After using Keepass and Kaspersky password managers I have to say that Proton pass has been the best one I have used so far. It integrates well with my browser without being too intrusive. It auto recognizes the page I am on and has the password handy for me. It syncs well to my phone and will even allow for app logins to be auto filled if I want it to. So far it has been easy to use and works as it should.

Fantastic password management, and a total bargain if you have the Proton plans which include this. A no-brainer!

It is a great password manager. As a long-time ProtonMail user, I've migrated from the built-in Firefox password manager to this as soon as I saw it :)

On the other hand, the product is not (yet) perfect, there are some areas where it could be improved:
- automatically locking the vaults after a certain time.
- passwords weren't filled in in basic authentication popups created by the browser which is a bit inconvenient sometimes
- the difference of the Proton Plus vs Unlimited feature sets feels a bit too big (at least supporting more than 1 vault would be nice in the Proton Plus edition). Vault sharing does not make do much sense when there is only one vault available.
