Add this

server.servlet.session.timeout=86400

to /home/rundeck/server/config/rundeck-config.properties to increase duration of user sessions to 1 day, so users will stay logged in longer.

If running in docker you need to set the RUNDECK_SERVER_SESSION_TIMEOUT variable. Example from docker compose file:

---
version: '3'
services:
    rundeck:
        ...
        environment:
            - TZ=Europe/Berlin
            - RUNDECK_SERVER_SESSION_TIMEOUT=86400
       ...
...
