The easy method:

If your controller is installed on a 64bit operating system (default for recent versions), you should have no trouble following this method.

Download Robo 3T from this link

Install and create a profile for your local server, and port number 27117

Connect to it, and in the left pane expand “ace” and then “collections”

Right-click on “admin” and click “View documents”

Open up this link to QuickHash.com

In the “Input data” field, type the new password you would like to set, and in the “Salt” field type 9Ter1EZ9$lSt6 and click Generate and your new password hash will be shown in the output field.

Copy the output value from QuickHash, and head back to Robo 3T to paste it in the “x_shadow” field.

Head back to your UniFi login screen, unter your username and your new password and you should be straight in!
