There is one function called "password protect directories" in cpanel. I wonder if i can use this function to set double/multi username/password for one folder. I.e, i want to use password to protect a.com/admin. I set up two pairs of username/password. One is user1/pass1, the other is user2/pass2. Now if i want to open a.com/admin, i should input both of above username/password. First time, i should input user1/pass1, after this, i should input user2/pass2. Is this possible? If i can not do it through cpanel, could i modify the .htaccess file to do this?
