The first thing to check is whether or not your Blackboard login works on a web browser. When you try to log in to your school's Blackboard site, are you able to login successfully, and then can you access your current classes?
I've successfully logged in on my web browser
Then those exact same credentials should work on the Blackboard Mobile Learn app. Please contact the Blackboard Support Team - make sure to include the URL of QCC's Blackboard site where you can login successfully! We will start investigating your issue right away.
I can't login on my web browser
Then you won't be able to login to the app either. If this is the case, please reach out to QCC's IT Service Desk so we can help you with account issues like this.
