I'm signed in to Gmail automatically

Internet Explorer's 'AutoComplete' feature automatically logs you in to Gmail if it's enabled in your browser's settings. If you don't want to use this feature, please follow these steps:

  1. Click the Tools menu at the top of your browser, and select Internet Options.
  2. Click the Content tab at the top of the dialogue box.
  3. Select the AutoComplete... button, and then click Clear Passwords. (You can prevent IE from storing your passwords in the future by unchecking the box next to User names and passwords on forms.)
  4. Click OK.

The next time you sign in to Gmail, you'll need to enter your username and password.
