The KFU Banner sign-in link
The official link is my.kfu.edu.sa2, and you sign in with your university account, not a separate account for the system.
What you do in Banner
Banner is Ellucian's student self-service: course registration with add and drop, the class schedule, grades and the academic record, holds on the account, and document requests. Faculty get a self-service of their own for grade entry and class lists.
Registration, add and drop open on the dates in the university's academic calendar, so if the registration button is missing, check the calendar before you contact support. Grades appear once the college approves them, and the academic record and documents are requested from the system itself or from the admissions and registration deanship, as the university publishes it.
When sign-in fails
Your Banner account is your university account, so a password comes back from the university, not from the system. At KFU that is Customer care1. Check first that the account is active, that the password is the one that opens the rest of the university's systems, and that you are on the official link rather than a search result.
The rest of KFU: portal, email and learning
The same account opens the learning system (KFU Blackboard) and university email. Every sign-in link is on the KFU systems page.
For faculty
Grade entry, class lists and section schedules sit in the faculty side of the same system, with the staff account. The KFU systems for faculty and staff: Staff email1.
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.
