I don't have a wifi password for my extender AC750 EX2800

[Kobe_James17]

I am having one issue about the password for the extenders network, it was never given to me. I don't know what it was to begin with and I don't know how to change it. My extender is an AC750 dual band (if that matters).

The default wifi password should be on the label. 

Or factory reset it and using the installation assistant for setup. 
To factory reset, push and hold the reset button for 7-15 seconds while powered on. 

Here's a video of how to use the assistant.
