I use Buttercup, because it's real open source, and because it stores your encrypted passwords by default on your machine and not in the cloud -- but Bitwarden is a good alternative too, from what I can tell: Dump LastPass for open source Bitwarden https://www.theregister.com/2023/01/16/dump_lastpass_bitwarden/
For password protection, dump LastPass for open source Bitwarden

After the security breach last summer, staying put is playing with fire

@BrideOfLinux what do you do with all the passwords you have stored? I have LastPass but I'm afraid to get rid of it because I don't know if I can transfer my passwords
@CaliGirl @BrideOfLinux You can. I exported from LastPass and imported into BitWarden and it worked well.
