Do you have a Microsoft account , Hotmail account or Outlook.com ( the online email account service from Microsoft) and wonder if someone else has access to your account ( they may know your password).
First log onto your Microsoft account at Microsoft Account
Then look for your Recent Activity Page
If you notice that you are logged on somewhere where you are not , then it is time to examine your security settings.
- Change passwords
- Turn on 2 factor authentication – you should do this anyway – give Microsoft your mobile phone number it will keep you secure.
