Lastpass exposed encrypted passwords in 2022

Yes, that's bad, but attackers would still need to break the encryption. Nobody does that, except maybe state level actors, and if you're worried about that, you wouldn't use commodity password managers.

1Password app had a bug where it didn't clear master password after logof

I think you're talking about this study:

On the negative side, the master password remains in memory when unlocked (albeit in obfuscated form) and the software fails to scrub the obfuscated password memory region sufficiently when transitioning from the unlocked to the locked state. We also found a bug where, under certain user actions, the master password can be left in memory in cleartext even while locked.

To exploit this, the attacker would need access to the memory of the device and know how to find the password in memory. It's certainly not ideal, but it's also not very exploitable.

The newer version is worse in this regard, but it still requires that relatively advanced exploit.

In the conclusion:

However, each password manager fails in implementing proper secrets sanitization for various reasons.

This isn't unique to 1Password, it's probably common across password managers. Unfortunately BitWarden wasn't part of this research because I'm interested to know how it fairs here.

That said, I don't use or recommend either LastPass or 1Password because they're not FOSS, I just don't like FUD. I use and recommend Bitwarden because it's audited, FOSS, and competitively priced.
