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

@BrideOfLinux Did you see this? Not quite as bad as the LastPass hack but still concerning. https://grahamcluley.com/ugh-norton-lifelock-password-manager-accounts-accessed-by-hackers/
Ugh! Norton LifeLock password manager accounts accessed by hackers

If you use Norton lifeLock as your password manager, your account may have been compromised. Learn more now.

@cmccullough No, I hadn't seen this. Very much a cautionary tale, isn't it.
@BrideOfLinux It certainly is.
