It might have to be setup by an Airbnb host but the past few places I've stayed at had the ability to press a button inside the Airbnb app to automatically connect to their WiFi. Definitely saves some of the less tech-savvy hosts from having to figure out how to create a WiFi QR Code and print it out

Idea: make one for each AirBnB you stay in. If you don’t have access to a printer while you’re there email them a PDF.

This right here. I've done the same. It's absurd the level of password hoops at some places. I appreciate the secure password, but when it's hand written in marker and faded it can be quite frustrating.
