I have an IPad of model MB292LL but I am unable to login with my apple ID. After entering the ID & password it pops up the message "Type your password followed by the verification code shown on your other devices." Now where do I find the verification code.
I'm guessing that you did not provide something to get the verification at? Did you ever have another Apple device? Take a look at this support document for information about this process. Two-factor authentication for Apple ID - Apple Support
It would seem that you have 2 factor authentication for your Apple ID and you should have a device that you used to complete that task and you should get a text if it is a cellular phone. That would come to you and you would enter that number. That is what they are referring to.
But what's the solution now I don't have apple phone & I wanted to login IPad also, is there any other way to find the verification code.
