MikroTik Router --- How to add user-manager package into the RouterOS 6.37

According to the MikroTik document, the User manager is a management system that can be used for:

•     HotSpot users;
•     PPP (PPtP/PPPoE) users;
•     DHCP users;
•     Wireless users;
•     RouterOS users.

Due to it is a separate package, this package is not installed in RouterOS by default if we log in the MikroTik Web Management by using the web browser next to click System --> Packages link.

MikroTik User Manager can be downloaded from the MikroTik web site download section .  To find the package version is the the same as the RouterOS one next to download Extra packages

.

and extract the compressed file to the safety path, we will find one file user-manager-xxx-xxx.npk

In the Winbox web environment, we will choose Files menu and Explore ... button

Select this package for uploading this file.

and Reboot it

So do that we will see it in the package list now.

Due to the default user 'admin' without password, we have to launch the MikroTik terminal for setting it.

Then we can change the password for the 'admin' user by using the /tool user-manager customer set admin password= command. (# 1)

So do that we can log on customer web interface by connecting the http://Router_IP_Address/userman URL.

Reference :
(# 1).    If we don't assign a new password for 'admin' user, the web interface cannot be login if use the empty password.
