QR codes, I printed a bunch on shipping label paper and stuck them on the walls near light switches, the entrance, etc. You can also do them with NFC readers for phones but that's more expensive and you need an NFC writer.

Just need a phone with NFC to write tags - you really just need the tags (which arent all that expensive).
Pretty sure the Home Assistant app has the ability to write tags - I made a tag that triggers a discord message when my dogs meds run low so I remember to order them
I have a thermal receipt printer that I use for printing the WiFi QR codes. I wrote a simple Python script using the escpos library.
True! NFC is actually a pretty convenient way to do it. No need to type the password every time
