It might not be a good idea to put your Wi-Fi password into a third-party website. I much prefer DIY solutions like the one at <a href="https://kmanc.github.io/be_my_guest/" rel="nofollow noreferrer">https://kmanc.github.io/be_my_guest/</a>, where the password is rotated and the QR code automatically displayed on an E-Ink display.
