If you sign into Google Mail from multiple computers, but are worried you may have forgotten to sign out of one, you can sign out remotely. At the bottom of your inbox, you’ll see information about the time and location of the last activity on your account. Click “Details” to see whether your account is still open in another location and “Sign out all other sessions” to close other open sessions.

Google Mail display feeds (news headlines and blog posts), ads and other information in the Web Clips section at the top of your inbox. There are feeds chosen by default, but you can customise yours by clicking the “Web Clips” tab in Settings.

If you regularly use Google Mail on unencrypted wireless connections at coffee shops or airports or university halls, then you might want an additional layer of security. Check the option in Settings to “Always use https”, and we’ll ensure your email is always encrypted. Note that no matter what, Google Mail always uses https to protect your password when you log in, but because https can make your mail slower, we don’t use https once you’re logged in unless you ask for it.
