Stop making ads ! You’re loosing your Followership

This should have been marked as an Ad

knew this was an Ad at 'we all hate passwords'

It’s always such a pain!! Thanks for the refresher

And for the rest of the possible users that don’t have google, Facebook or apple accounts? The % is so low we can ignore it? Or we will have to implement a “simple” login anyway?

Well, that depends on your particular application. For example, on my course website, I only use Discord because every student must have Discord. Many applications still offer the option of custom credentials. Many applications only offer SSO. Assuming you add support for the largest providers (Google, Facebook, Apple, Microsoft...), the probability that one of your potential users doesn't have any of them is minuscule.
