Lepseawhat is the most scure password manager?
The most secure thing to do would be to host your own server. You can do this with Bitwarden. Remember though that if you lose your server, you lose your passwords. You can also just use Bitwarden and their cloud service. It’s free and open source.
I can’t really host my own server right now (maybe later when i have my own place) and after a bit of research bitwarden is the best free option but somehow it have 3.4 ish rating in my region
