Is it that you have forgotten your email Id and if you have forgotten that then try to recall it. But, if you have forgotten your password then you need to reset your password and for that follow these steps:
>> Open the official website of Hotmail.
>> There you will find an option which says “can’t access your account”. Click on that option.
>> A new page will open. Fill in your account details and the characters shown in an image below.
>> Click on the option “Next”.
>> Then it will ask you some of the security questions and you have to answer them correctly. After then you will be able to reset your password.
Hope this will fix your issue.
