Accessing Multiple Google Accounts

If you go to google.com or email.williams.edu you may find that you are already logged in to a personal gmail account. You can either log out of the personal account and then into the Williams account, or you can simply log in to the Williams account and have both accounts available simultaneously.

Many find the simplest approach is to access their personal gmail account using one browser and their Williams gmail account on another (for example, Firefox for personal and Chrome for Williams).
