wool, the first answer is totally nonsense! You set up an administrator, so you need to verify it. If you haven't changed your password, the login number and password are both attendance numbers! If you really don't know, you can clear it!

the computer must have Access, a suite of office23 or office27 installed. Open the shortcut of the attendance management program on the desktop, and click Find Target. Find the USERINFO table in the interface where the att2.mdb file reappears, double-click to open it, and delete the contents of the two fields, namely, SECURITYFLAGS and PASSWORD! If there is no software to open access on the computer, then contact your supplier, send the file att2.mdb, and you can restore it after clearing the password!
