I forget icloud password and my phone number that i used before is no longer with me in my old iphone5

Hi Rgrakhnoukh,

Thank you for using the Apple Support Communities! We understand you're unable to log into your iCloud Apple ID account. We're happy to help.

With you mentioning you no longer have the phone number that was used with that Apple ID account, it sounds like you had either two-step verification or two-factor authentication set up as an additional layer of security, where you have to use a verification code to complete the sign in process. Does that sound familiar?

We see you've checked out If you forgot your Apple ID password. "* If you permanently lost your Recovery Key or access to your trusted device, you can't change your password."

"If you use two-factor authentication and can’t sign in or reset your password, you can regain access after an account recovery waiting period." Quoted from within: How to use account recovery when you can’t reset your Apple ID password

Best regards.
