用户名和用户ID有什么区别?

User IDs may be University Registry numbers or other identifying numbers or codes assigned to students, whereas a User Name is required for logging in. Because User IDs may be confidential, a privacy setting exists in the Server Configuration tab of the Admin pages which allows these characters to be concealed in all student experiment sessions. If a password has not yet been assigned to a new student, they will be required to verify their User Name with their associated User ID when signing into LabTutor for the first time, before being prompted to create a password.

此信息对于LabTutor V4.0和更高版本是有效的。
