This Pi Pico project can generate guest Wi-Fi networks complete with QR logins

 

Having friends over is all well and good until one of the freeloaders decides it's not enough to eat my food anddrink my drinks—they also want access to my Wi-Fi. Now comes the awkward moment of verbally explaining the niche reference in your Wi-Fi username, and your equally convoluted passwords.

No, that's the number 2, not the word too. No, not "two" or "the number two". You know what, maybe just let me do that for you. It's almost as hard as explaining what Wi-Fi actually stands for(opens in new tab).

Those smartest among us have already dealt with this issue. It's not uncommon practice to have a password written down for people to copy, but the real tech foes use QR codes. These can be set up to automatically join a network just from the data contained within the code, so no manual entry has to be completed.

Instead, having one of these bad bois printed out hanging around on your coffee table means guests can just scan and get instant Wi-Fi access. There's no guilt of asking, or frustration of giving: just speedy internet access within seconds.

This is all well and good, but maybe hold off on painting that QR code feature wall in your living room just yet. Good security practices dictate that passwords should be changed regularly. For a family Wi-Fi this may not be a concern of yours, but regardless, changing your settings can make this code unusable. This is precisely why Predrag Mijatovic's Pi Pico project(opens in new tab) (via Hackaday(opens in new tab)), while a bit fiddly, provides a pretty interesting solution.
