If it is wrong, you can try several times to correct the problem before you can change the password.
Methods: 1. Try the initial password (the initial password is generally the same as the ID number of the card, or the number of digits of the ID card ranges from 12 to17); 2. The email address has been set in the modification of the personal information of My Library, and the validity of the email address has been verified. If the password is lost, it can be retrieved through the mailbox; 3. 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 doesn't solve your problem, please bring your one-card voucher to the technical department on the fifth floor of the library for modification.
