So I bought an Apple watch on eBay, it had an activation lock, so I contacted the seller. They gave me email and password. It says it's wrong, they told me to try logging in to icloud to check, I used that email and password, it actually logged me into icloud.com, but due to 2 factor I can't move on . I'm pretty sure the same icloud account as the first letter is the same and the same number of characters, add the person I bought it from, has 800 feedback, all positive, so not likely to be a scammer. Any ideas?
