I can't speak about the other password managers, but 1Password's architecture ensures even 1Password can't see any of your credentials. It's E2E Encrypted.

I've been a 1Password user for over a decade. It's user friendly, and I'd rather not have the responsibility to self-host my company and extended family's credentials.

Bitwarden is also a zero knowledge architecture built on E2EE; I would presume that is the standard in the industry.
