Hello @BriannaNewburn
I hope that you were able to get signed in to Canvas. It sounds like you need to perform a password reset. This is going to be a different process for different schools and also depends on if your school is using their own authentication method or if they use Canvas's. See if this guide helps - https://community.canvaslms.com/t5/Student-Guide/How-do-I-reset-my-password-as-a-student/ta-p/409
If you don't see the option for forgot password then that most likely means your school manages the account, in which case you should reach out to your school's IT/Help Desk for assistance. Hope this helps!
