With my apple icloud free mail account, account is -- well made 2 from it.. one myname 33 @icloud.com and other with another name before icloud.com.

I want add third pseudonym, but can't remember now how to do it, rusty, ..... non intuitive. You go into mail, account and then...? If anyone knows the steps... Thanks

Use Email Aliases On Icloud.Com — Apple Support

A possible more secure alternative would be Hide my email for sign in with Apple — APPLE support

Thanks Joe, first link is what I think I need, the alias method.. Will report back if get stuck..

2nd on how hide email kind of over my head. Though, there are a few place maybe I would like that.. though probably easier to just have a dummy gmail/ forwarded email? Looks sort of complicated, but maybe I'm wrong.

The second method is actually pretty easy, but the site has to offer Login with Apple ID as an option, like the more ubiquitous "Login with Facebook" and "Login with Google". Login with Apple is new but the number of sites is growing.
