I have been running a SaaS for ~10 years used heavily by people 65+ and a lot of them are tired and frustrated about remembering the domain/path to login screen and then which email/password they used, having to go through the whole forgot-password-flow, etc. I have tried simplifying this as much as i can but I feel like there must be better options. Google sigin in is confusing for them because they get thrown into Googles horrible UX flow where they might have multiple accounts and they don't like when the website suddenly changes.

In general, what is the best way to simplify the auth UX for this group of users? Is there any UI libraries out there targeting this group more specifically? Any good web examples you know of?

thx
