I forgot my iCloud ID and password
I forgot my iCloud ID and password, and my iPhone just got reset. It's asking me to enter my iCloud ID and password to reactivate my phone, but I can't remember. I have tried entering my information but it leads me to another account I own. It gives me a hint on what it is, but not enough. If anyone knows how to find a lost iCloud ID and password without entering information, please let me know as soon a possible.
iPhone 5c, iOS 9.3.1
