If you want privacy, sadly, you will have to pay. I am currently using Proton Pass (special offer 1$ monthly), you get a good password manager, plus unlimited email aliases.
Proton is also known to be one of the best Email Providers based on good privacy.
I mostly pay for the unlimited email alias, the password manager is free by itself.
I was using Bitwarden before, but the unlimited email alias sold me on Proton Pass, and 1$ monthly is nothing for not getting spam anymore.
