There are two user accounts in Windows 10 Desktop Computer. Both are Microsoft outlook accounts. One is administrator and another is user.

I can log in user account, abcd@outlook.com and I can browse Internet as well. But I am not able to log in administrator account, xyz@outlook.com. It says password is incorrect. I can log in xyz@outlook.com on another computerís browser with the same password.

Please let me know. How to resolve it?
