I use 1Password atm, but want to switch either to Proton or something selfhosted.

I’m going to suggest the lessor known option, Enpass, I’ve used it for maybe eight years? I paid a one off fee at the time. It’s multi platform, windows, iOS, Linux etc. It has browser plugins, there’s a Flatpak option so it’s handy for my Linux distrohopping. It supports passkeys and one time codes and you can store the data in any cloud you want…

Been using the Firefox password manager ever since I’ve been using Firefox on all devices. Used Firefox clockwise before that. Planning to switch to a self hosted vaultwarden+bitwarden setup. Any guides or pointers are welcome.

KeePassXC here. Locally encrypted, Locally stored, cloud backup of an encrypted file, synced with SyncThing to mobile devices. I will never trust nor recommend a cloud based manager with all the breaches.
