I wonder what is the urgency and/or importance to create such a decentralized password manager? I don't get whether the usability of such a decentralized password manager is feasible or not.

What I mean is I pretty much enjoy using Bitwarden, I tried to maximize the habit to securely protect my data as a whole, and so far so good. Especially since I am comforted to use the application in terms of ease of use.

I tried to comprehend your post, it looks like that you are more describing about the password generator rights? I don't get the point that it can be used as a password manager, could you elaborate it a little bit?
