General
Use different usernames and passwords to different online sites, especially important sites which hold financial or personal information. If you use the same username and password everywhere, and it's stolen, you could lose access to all of your accounts.
If you are checking your Hotmail account, signing into Xbox.com or using another service which requires you to use your Microsoft account on a public computer such as an Internet café, take caution in that these PCs may not offer the same protection as you do at home.
We recommend that if you are looking to use a public PC that you use a single use code instead of your password when signing in with your Microsoft account.
