What if I would like to delete my child’s old Apple ID, but I forgot their password, and I don’t have the same phone number to try and access the Apple ID?

If you find you can’t sign in, reset your password, or receive verification codes, you can request account recovery ( How to use account recovery when you can’t reset your Apple ID password - Apple Support ) to regain access to your account. Account recovery might take a few days or longer, depending on the specific account information you can provide to verify your identity.
