Sounds nice, though ideally password sharing should never happen and is a security nightmare. Reallistically we know however there are situations where it's the easiest or only way to do something.
So when I e.g. revoke some contact access to a shared password I absolutely have to change the password as well, since I have to assume that contact made a copy of it somewhere else.
Next on their roadmap: Proton Pass web app
I'm looking forward to it! I'd like to manage my passwords in a full web app, instead of just the mobile apps and extensions
This is a game changer, I've been a strong advocate for Bitwarden but this allows you to share with users outside of your organization.
