My username and password are saved on the login page
You may sometimes be logged in or have your login information displayed automatically because your username and password are stored in your browser's cache or settings.
If you don't want 'AutoComplete' to automatically log you in to Gmail, check your browser's settings or preferences and adjust them to make sure your passwords aren't being saved.
