Seems like we neeed more context? If you simply forget your password often, you can utilize password managers like LastPass or C2 Password to help to memorize credentials
I really dislike Google SSO because it doesnt seem safe and has no advanced features like password sharing, or support of saving information outside of credentials and payment info.
theres this new service called C2 backup that supports file and transfer encryptions, while requiring private keys from users to access files. Pretty happy about the security, as well as the usability aspects so far
