Bitwarden. Very straight forward and open source
I just use BitWarden and it's close to perfect.
I did a write up on it for anyone interested.
EDIT: docs: https://bitwarden.com/help/change-client-environment/
I recently picked up my adult daughter’s phone and tried the password I knew she used as a teenager, it is still the one she uses. I’ve tried to get her and other family members to use password managers and better security practices. It’s like talking to a brick wall. They all think it is too much work. Of course, these are the same people that post their entire lives on social media.
