Default Password of PLDT Router AN5506-04

The default password of PLDT router admin account (“adminpldt”) keeps on changing every now and then. As a result, the default passwords published on the internet do not work anymore. The default password used to be “1234567890”. Later, it was changed to “0123456789”. Again, not very long ago, it became “6GFJdY4aAuUKJjdtSn7dC2x”. As of 10 October 2019, in my router AN5506-04-FA, the default password is:

Default Username: adminpldt
Default Password: z6dUABtl270qRxt7a2uGTiw

What follows is a step by step guide on how to find out the default password for PLDT routers, for both the “admin” and the “adminpldt” accounts. As an overview, first, we need to enable the “telnet switch” on the router’s web admin interface by logging as a SuperUser. Finally, we display the passwords for both the user (“admin”) and the admin (“adminpldt”) accounts by using a program called telnet.

Step 1

Open your internet browser and then type https://192.168.1.1/fh on the address bar.

Step 2

Type in the default username and the default password of PLDT router SuperAdmin account.

Administrator: f~i!b@e#r$h%o^m*esuperadmin
Password: s(f)u_h+g|u

The old super admin username was “fiberhomesuperadmin” and the default password was “sfuhgu”.

Step 3

Click “Debug Switch” in “Device Management”.

Click the “Enable” button on the “Telnet Switch”, then click the “Apply ” button below it.

Next, click the “Enable” button on the “Web Admin Switch”, then click the “Apply” button below it.

And finally, click the “Logout” near the top right of the window.

If it says that ‘telnet’ is not a recognized command, then, you will need to enable it by searching for “telnet”, and clicking on the “Turn Windows features on or off”.

Step 8

Password: gepon

Step 9

Config# cd web

Step 10

To display the password for the “admin” account, type “get web user username admin”.

Config\web# get web user username admin

Step 11

In the same manner, to display the password for the “adminpldt” account, type “get web admin username adminpldt”.

Config\web# get web admin username adminpldt

Below is the screenshot of whole telnet session, showing the hacked “admin” account password and the “adminpldt” account password.

Take note that based on the display above, my password for the “admin” account is “12345678”. Also, my password for the “adminpldt” account is “admin123”.

However, if you reset the router to the factory defaults by pressing the reset switch at the back of the router before doing the procedure outlined here, you should get the default password for PLDT routers: password “1234” for the “admin” account, and the password “z6dUABtl270qRxt7a2uGTiw” for the “adminpldt” account.

Cheer and Enjoy!
