How about apps which only have the option of signing in with Google or some other social / 3rd party provider? Do you also not use other services like Microsoft's, Apple's, Facebook (Meta)'s? How do you in that case sign in?

Most service providers support “sign in with email”. I’ve yet to find a service where no provider has this option.

I don't know of any. Examples?
