Tangentially related, but is there a way to recover the default password, or remove the password?

[jMyles]

I'm working on a WVA that I purchased new in 2016, and it powers on and broadcasts its SSID, but I don't know the password, or its default password.

I think I have long since lost the QR code.

Is there another way to recover the password, or to change it to an open AP?
