If your password is right, then the problem could be on Hotmail's end. Check the service status on the company's website. If it's green and you are still not able to log into Hotmail, someone may have hacked your account, in which case you will need to change the password.
It is also possible that your Hotmail account has been temporarily blocked due to unusual activity. You may require a support-assisted unblock that can take 24 hours or longer. A link on the bottom of the "Outlook.com Account Help" page will take you to a support page where you will need to enter some information into a form. A Microsoft customer service representative will contact you via email, either with instructions on how to unblock your account or requesting further info.
