Question 1

Do guests see my Wi-Fi password?

Accepted Answer

The password is stored in the code, and a determined user can read it with a scanner app. Treat the code with the same care as the password itself.

Question 2

Which security types are supported?

Accepted Answer

WPA/WPA2 (the common case), WEP, and open networks with no password. Hidden networks are supported too via the hidden-network option.

Question 3

What happens if I change my Wi-Fi password?

Accepted Answer

The old code stops working — the credentials are baked into the image. Generate and print a new code after any password change.
