Instead of people constantly asking for the password for your wifi, there should be an RFID/NFC tag mounted on wall that can be scanned which will give the latest password. Perhaps having it next to refrigerator or something so it can't be scanned from outside. They just use their phones NFC reader to get the info and be online.
This way you can change the password whenever, but your friends who come over often can still use your wifi without you having to tell them the strange sequence. This is especially handy if you can't remember your password when asked.
An expanded module could also provide time limited passwords, so that people can have a password when they come over but you don't have to give them the permanent passcode. Handy for parties with lots of strangers that don't come over very often.
