Canvas will always use your Student ID number as your username. If your Canvas account was created after December 1, 2016 your default password will be the first 8 letters of your last name. If your last name only contains 3 letters, repeat those letters until you have 8. For example, if your last name is Reed the password would be reedreed.
If you need to download the Respondus Lockdown Browser, you can do that here. Many students will be required to use it when taking tests at home. If your instructor does not use it you will not be required to download and install it. Lockdown Browser can be found on Library Computer labs for your use.
