Hello, I have forget my apple ID along with password. How can i get my apple id?
I have an invoice of purchase from the official store of apple.
MacBook Air (2018 – 2020)
Check these articles to find the Apple ID used to set up the iPhone, reset the password and erase the phone to set it up again:
If you forgot your Apple ID email address or phone number - Apple Support
If you forgot your Apple ID password - Apple Support
If you forgot your iPhone passcode - Apple Support
In case this does not work, and you have proof of purchase documentation, you can start an Activation Lock support request.
