Cafe turns its WiFi password into complicated math equation

Yaya’s Thai in San Antonio has turned its password into math equations instead of setting a long and complicated password. If one needs access to free Wi-Fi, all they need to do is find the right answer to the equation.

This quirky idea was from 2016 and is being discussed and explained again on Reddit. While trying to access the internet, the user was faced with math equations that weren’t easy to solve.

Recently, a Chinese university come under a lot of scrutinies after it asked students to solve a calculus equation to get the Wi-Fi password.

A member of PR staff had told Beijing News.“It aims at promoting the charm of higher mathematics and encouraging the freshmen to work hard.”
