Macbook Pro (OS X) won't let me login to iCloud
I need to sign into my iCloud on my MacBook Pro, but every time I try, it says my password is wrong. I tried the same password on my iPhone and it worked just fine. I reset my password twice and now every time I try to login on my MacBook it says I need to go to iforgot.apple.com. However, once I am at that site, all it will allow me to do is reset my password or questions, not unlock my account. Hence why I reset my password twice to see if that will help.
If anyone could share some knowledge on how to fix this, it would be greatly appreciated!!
MacBook Pro, OS X El Capitan (10.11)
