There's plenty of websites that claim to teach how to hack a hotmail password but this is usually a trick by bad guys so they can hack your hotmail. Others will claim to provide software to crack and hack hotmail accounts but you will end up installing a Trojan or other type of malware. Hacked hotmail accounts will annoy the owners contacts, because the hacker will send out spam emails without your knowledge, so it is recommended that you check your hotmail account activity on a regular basis.
Scammers will also steal your hotmail password via phishing sites or by sending spoofed e-mails. Be very careful when you receive or view a link that pretends to be a Windows Live Hotmail website or messages supposedly from the Live ID support team.
When someone has hacked your Windows Live Hotmail password, immediately do the following steps to get back the compromised account:
Please note that, according to Windows Live Team, a temporary Windows Live Solution account will be created for you. The temporary account means they will setup a private forum where you can discuss the compromised hotmail account with their support agent. Your answers to reset or recover the hacked hotmail password or account will be stored in the private forum. You can return to the forum to check the status of their investigation. It's basically just a support ticket through a temporary Windows Live Solution account.
If you have entered your mobile phone number in Hotmail, it can help you recover your compromised account, because only you have access to your Mobile PIN. If you want to change the PIN code, go to https://account.live.com/ChangeMobilePin.aspx. Updating your account information will also help to recover your hacked hotmail account because many people forget what they've entered in their account and this will slow down anyone trying to investigate or recover a compromised hotmail password. People who moved to another location should update the account information to help the Support team at Windows Live identify you. It's also an important part of securing your data when you continue to update your Windows Live Hotmail account or Windows Live account. If you've linked another Windows Live ID to your Windows Live account, make sure that both are accessible to you and that the passwords and account information are up-to-date.
To continue using a secure Hotmail account, never share your password with anyone, don't sign in on computers that you don't trust, especially public computers such as library, school or internet cafes that might have Trojans, keyloggers or another malware infection. Make sure the computer has an anti-virus program. If you have to access Hotmail using a public computer, login by clicking on "Get a single-use code to sign in with" so that Windows Live will send an SMS to your registered mobile phone number. If you have not registered a mobile phone number with Windows Live, you cannot use this option. Finally, remember to login to Windows Live services using SSL connection.
