1. In the modification of personal information in our library, a mailbox has been set and its effectiveness has been verified. If the password is lost, you can get it back through the email address.

2. Log in to the "Digital Campus Portal" with a one-card account and password, and directly open the "Library System" in "Personal Information", that is, "My Library", so that the password of "My Library" can be modified and the mailbox can be reset.

If the above situation still can't solve your problem, you can go to the official customer service to solve your problem.
