Use the correct starting point
If your organisation uses an LMS, begin from that system and its exam link. For an exam assigned directly in TrustExam, the general guide uses app.trustexam.ai and credentials supplied by the organiser. A new unrelated account will not restore an existing invitation.
Check these details
Confirm the scheduled date, time zone and access period in the invitation.
Enter the assigned login exactly, without extra spaces. Use the email, phone or identifier specified for your programme.
After signing in, open Assignments and look for the correct exam.
If an invitation code is rejected, ask the organiser to check its expiry, remaining activations and whether it is assigned to you.
“User Not Exists” or no assignment
For some programmes, accounts activate when testing starts. During the active testing window, the organiser should verify that your participant record and group membership are correct. The same message can have different causes; it does not by itself prove that your account was deleted.
If access is still missing
Contact the organisation that invited you. Give the exam name, scheduled time and exact error. Use the designated support channel for any identity details requested to verify your record. Do not send a password or a private invitation link through a general enquiry.
