Duo Setup

If ��ǳ�’r�� a high school dual-enrolled student taking ��ԭ�� classes, follow the steps on this page to set up the Duo app. This is your second step into college systems.

Set up Duo to protect your ��ԭ�� account.

Duo keeps your grades and info safe, just like locking your front door.

After you type your password, Duo asks you to approve a notification on your phone or enter a code. This way, only you can log in — even if someone guesses your password.

Duo example: If you log in for homework on Canvas, a message will pop up on your phone — just tap “Approve”.
