Activate Account

After registering, you will receive an activation email at the email address you entered during registration. Select the link in the email to activate your account. 

Find instructions for what to do if you do not receive your activation email.

Change Username

Once a UC San Diego Online username has been created at registration, it cannot be changed. 

You can instead create another account using a different email address to have a different username.  

If you would like to use the same email address for the new account, you will first need to associate a different email address to your existing account. 

You can edit your email address from your Account Settings page. Select the dropdown arrow next to your username in the upper right corner of any page and select Account.

Remove the current address from the email field, and type in your new email. After you click out of the email text field, you will see the message "We've sent a confirmation message to 'email address'." Click the link in the email message to update your email address.

Once updated, your original email address will no longer be associated with your current UC San Diego Online account, and will be free to use on the new account with your new username.

Username Belongs to an Existing Account

Every UC San Diego Online account must have a unique public username. Your first choice or choices may already be taken. If your desired username is taken, the following message appears:

We couldn't create your account. It looks like onlinelearner belongs to an existing account. Try again with a different username.

Note that your username can include letters and numbers, but no spaces or special characters.

If you continue to have trouble finding a username that works, we recommend adding a random number onto the end of it.
