How do I change my default email address in my user account as a student?
Your default email address is used as your main contact method in Canvas and is added when creating your Canvas account. Email addresses are used to create Canvas notifications; they are not used as a contact method for other Canvas users.
If you add another email address as a contact method, you can change your default email address in Canvas.
Open User Settings

In Global Navigation, click the Account link [1], then click the Settings link [2].
