Hi, I installed Craft on my iPad. When I launched the app, it asked me to confirm using email address or via Apple. What is this all about? Which option is recommended? Thanks

It is probably asking that to set up an account. Signing in with Apple option is more secure and prevents the company from knowing your real email address or putting your sign in credentials at risk.

Thanks. I don’t know much about iOS app. At first I thought signing in with Apple option would give them more information about me such as telling them my Apple ID.

So doing that won’t give them access to my Apple account? Is such signing in with Apple option means Apple becomes the middle man between me and the app developer? In general, could developers make fake signing in with Apple option to get private information?

No. Even if you give someone your id and password you still should have two factor authentication.

I signed in with Apple. Then Any.do keeps sending me message everyday. If I hit unsubscribe, will they know my email address?

They’ll either already know your Apple ID email or the random one if you chose that option. You can only unsubscribe from something that knows your email one way or the other.

If I don’t want such spam happening again regardless of apps, what can I do? By unsubscribing from my email account, I may just confirm with them that they got my private email address.

Kind of scary. Better to delete that app. Who knows what else they are tracking. Can I complain to Apple?

After almost 6600 posts on a tech forum you come up with very interesting questions to be honest. Thousands of apps these days require you to create an account in order to function. As a side effect you often subscribe to their newsletter services. It’s up to you which alley you’ll pursue next but sending spam after explicitly unsubscribing prior can get the sender in some trouble in plenty countries.
You created an account with a company using Sign In with Apple. They have your Apple ID email on file as is expected (or the randomised email, only you will know which you selected). Wether or not you cancel your account and unsubscribe is up to you. And having your email on file is not tracking.

As an experiment I downloaded Craft and signed up via Apple with a private email address. I could see the private email address (randomnumbersandletters@privaterelay.appleid.com) in my Craft account area. I tried to send an email to that address from another email account and it neither is delivered nor did I receive a bounceback.

The "welcome" email from Craft was from differentrandomnumbersandletters@privaterelay.appleid.com address so I'm assuming that's the ONLY email address that can send emails to the private one given to me. I guess this is how Apple is preventing spammers from using potentially leaked email addresses.

I installed Any.Do on my iPad. Don't recall what happened but if there were a randomized email option, I would have chosen it.

Any.Do was also installed automatically on my iPhone. I just clicked on it and signing in via Apple or other options showed up. I checked on signing in via Apple account but it asked me if I would allow using my 'shown' email address associated with Apple ID to sign in. I guess I just signed in with the single available option when I installed it on iPad. Is that how they got my email address?

Why signing in with randomized email address was not listed as an option? Isn't this a 'must' listed choice required by Apple? So App developers can remove that option and makes using the email address associated with Apple ID the only choice to sign in via Apple?
