KeePass is a free open source password manager. Passwords can be stored in an encrypted database, which can be unlocked with one master key.
I've always hated the idea of using a subscription/cloud hosting for password management. I feel like I should have a LOT more control over that stuff and I don't really want to hand all my keys over to a company.
All my secrets have been going in a highly encrypted archive with a long passphrase, but obviously that isn't convenient on all devices. It's been fine, I can open it on any computer but it's not super quick. It does have the advantage of being able to put in multiple files, notes, private keys but it's not ideal.
Anyway, finally found something that isn't subscription, and has a similar philosophy - a highly encrypted archive file, and it's open source and has heaps of clients including web browser plugins so it's usable anywhere, and you can sync the vault with any file sync you like.
Thought you guys might appreciate the find, password managers have always been a bit of a catch 22 for me.
Note for android i found keepassxc the best app, and i'm using KeePassHelper browser plugin, and the KeePassXc desktop app as well as the free official one. Apps all seem to be cross platform.
I don't know if they fixed it, I hope so, but not long ago there was a very dangerous vulnerability that allowed an attacker to bring able to access the master password.
I was using it long time ago, then I discovered Bitwarden and I'm really happy with it. I suggest you to have a look, in terms of UI is better and can be self hosted too.
I think that vulnerability was a non-issue. Someone could get to your password if they had full access to your machine to run arbitrairy code. But if someone has that much access, it's already game over.
