Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows. I'm sorry that you're having this issue. It would be my pleasure to help you resolve this. You mentioned that you need to log in to the cloud. There are several cloud based services. May I ask specifically which one you're trying to sign into? For instance iCloud (for Apple products), Microsft One Drive(for Microsoft products), and thrid party services like DropBox.
