Bitwarden

The Ui is a bit lack lustre than its competitors and the customer support for free tier is okayish but other than that it checks all the marks.

open source and secure

Open-Source FTW

The mobile app is easy to use, the chrome plugin is even better

Très bonne application traduise en français

The free version of Bitwarden alone is leagues ahead of the paid versions of the popular password managers.

Best if you need a free password manager

Complex passwords, documents, notes, credit cards and papers: so many things, all important, only one place to keep them, but easy and very safe. You don't have to be a software engineer to use it

I'm happy to use it as a browser extension and as an android app. Paid version is cheap.
