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 https://kmanc.github.io/be_my_guest/, where the password is rotated and the QR code automatically displayed on an E-Ink display.
I have a design rule that I don’t print non-standard and stylized QR codes: maybe they work on expensive iOS devices but have you tried cheap androids?
