Some Wi-Fi passwords are really long and secure, making them tricky to enter into the field of the gateway configuration web interface. It would be super duper if we could visibly see the Wi-Fi password as we enter it into the text field.
A humble feature request. 
I don’t have a problem with that. Soft AP connection with the Gateway devices is pretty secure since they only allow 1 client connection at a time making a “man in the middle attack” pretty difficult to pull off.
Most generally if I have a long password like that though I simply copy and paste, but I can see the validity in this. I will discuss this with other members here to get feedback.
