Thank you SO much! This helped me get back into my Apple ID. It worked instantly. TT_TT
For me, I had been locked out of my Apple ID, and my phone had been disabled. It is my only Apple device. First, I had to go the Apple Store to get that sorted. Fortunately, they were able to at least get me back into my iPhone, since I had brought my proof of purchase with me. Then I tried account recovery, but I never got the second text with the information about how to actually recover the account. I even had my phone off during the entire period.
I tried your advice just now and am typing this post while FINALLY logged in to my Apple ID. THANK YOU!
Just like in AoiHikage's post, I went through account recovery and entered my phone number. When it gave the option to either use a phone number or a trusted device, I chose "trusted device", and I instantly got a message on my phone asking me if I wanted to allow my Apple ID to be unlocked. I said "Allow", entered my pin, set a new password, and I'm back in.
Again, THANK YOU!
I hope this confirmation can help others.
