More and more websites are asking you to sign up for free. Most of them, all they want is your email and then send you advertising either on the same website where you have registered, or even worse, third parties that have bought your "free registration".
What I personally do in these cases is use a gmail account that I use only for these records, and that I hardly ever check. This way I sign up with a valid account, and not "dirty" my personal email with spam. Now you can use your Apple ID to enter Adobe. And without receiving publicity.
Adobe just expanded access to its cloud, adding support for signing in with Apple. This new option serves both the Creative Cloud website and Adobe applications.
This new feature was added today unannounced by the Adobe company. It was the users themselves who were surprised and posted it on Twitter. It works exactly as you might expect, and gives users yet another way to sign in with their Apple ID without having to create a new account.
It is a session service similar to the way that Google or Facebook allow you to use your account credentials staff to log into third-party websites and applications.
If you use one of these two mentioned, Google or Facebook track your internet use, your activities, habits and location, and they can send this information to the new website where you have registered.
Apple is never going to do this. In this case of Adobe, for example, you can safely register with your Apple ID with the assurance that the Photoshop company will not receive any data from you that Apple has, not even the email address, which remains encrypted and hidden from third parties.
