Configure apache to use basic authentication using .htpasswd
https://httpd.apache.org/docs/current/howto/auth.html
or any similar method.

Write a script that can run a a service, pseudocode:
1- wait for a trigger, e.g. user pressing a button, 
   indicating [s]he wants to login 
2- generate a password, e.g. using openssl rand ....
3- generate a .htpasswd file using htpasswd -b ....
	https://httpd.apache.org/docs/current/programs/htpasswd.html
4- display the password on the display (off topic here)
5- back to step 1

configure systemd to start that script as a service (off topic
here).

Good luck, enjoy
