The KFU Blackboard (BB) sign-in link
The official link is lms.kfu.edu.sa3, and you sign in with your university account, not a separate Blackboard account. Students also call it BB, or LMS after its address.
The Blackboard app on your phone
The Blackboard app itself is on the App Store and Google Play1. It works with the university's own Blackboard server: pick KFU when it asks for your institution, then sign in with the same university account you use in the browser. Courses, announcements, grades and assignments reach you in it, and the features depend on what the university has switched on.
When sign-in fails
Your Blackboard account is your university account, so a password comes back from the university, not from Blackboard. At KFU that is Customer care2. Check first that the account is active and that the password is the one that opens the rest of the university's systems.
The rest of KFU: portal and email
The same account opens the academic system and university email. Every sign-in link is on the KFU systems page.
For faculty
The same app serves instructors too: course materials, assessments and student follow-up from the phone1. The KFU systems for faculty and staff: Staff email2.
After you sign in: student prices for KFU students
A KFU student verifies in tiswa with their university email and opens student prices on devices, software and subscriptions. Every deal is on the KFU student page.
