Bootstrap it with a shorter password:

1. Have the display show a 5-digit PIN (TOTP or something that changes every minute or few)

2. Let anyone connect to your network, if they go to a browser window it will show the capture portal

3. Enter the 5-digit PIN and press "enter" and the page will show the 30-digit password so the user can copy+paste

4. User pastes password into WiFi screen and logs in

Make sure to rate-limit this endpoint to prevent random PIN attacks.
