Apple ID password reset error: "not valid or not supported

Hi diasalehs

welcome to this Apple (user-to-user) Community.

Re: "Hello Apple Support, I’m having an issue with my Apple ID".

Seems you have posted your request for assistance where Apple Support is unlikely to see or respond to it. We are all Apple users, just as you are, in this community, and no-one here has access to your accounts or details in order to help. We can volunteer some useful info.

Re: "I get the error":

“This Apple Account is either not valid or not supported.”

Seems you have signed in to your iPhone with your details and not yet had them verified by Apple.

So am wondering if you have actually created an Apple Account yet:

If not: See Apple Support's YouTube video: "Create an Apple Account"

You can check whether you are signed in to your device with the correct Apple Account details: Go to Settings > Apple Account or {your name} > Choose or check the sign-in method.

If you have made setting changes you may want to:

Restart your iPhone - Apple Support to update them.

If you do already have an existing Apple Account:

Possibly the device you are using may not be one that Apple "trusts",

ie: a device that has previously accessed your account, and is listed there.

See whether Apple support's online article can help:

Re: 1. Check the status of this Apple ID on your system

Apple ID is now called Apple Account:

You can try logging in to an existing Apple account online:

(See link above for obtaining a verification code)

https://account.apple.com/

2. Help me recover or reset the password

For a forgotten password for an existing account:

Verify your account information to reset your password.

Re: 3. "Advise how I can remove this Apple ID from my device if recovery is not possible. I can provide proof of purchase for the device if needed".

If all else fails: Recovery of an existing account is generally possible. However it may take a few days:

Thank you for your thoughtful reply, as you try to help your friend.

I don't know for sure, but the iPhone with the Apple account that generates the "not valid or not supported" message may have been locked for security of the data on it. This could happen because of too many unsuccessful attempts to log-in, or to reset the password.

If so, the Account owner may need to prove rightful ownership of the account / iPhone to Apple, in order for them to remove the lock. Apple may need to know for sure it is not allowing access to unlawful use of the Apple Account / iPhone. Many people have financial info stored there, and that needs to be kept secure.
