Creating a nodered hash if runnning nodered on docker:

  docker exec -it node-red npx node-red admin hash-pw
  
Quickstart:

  docker run -it -p 1880:1880 --name mynodered nodered/node-red
  docker run -d -p 1880:1880 -v /data/nodered:/data --name mynodered nodered/node-red         #run in daemon mode
  
====Password====

  node -e "console.log(require('bcryptjs').hashSync(process.argv[1], 8));" my_PW              #create hash from "my_PW"                                     
  /data/nodered/settings.js                                                                   #search for "adminAuth" and edit "username" and "password" (enter hash from previous comand)
  
**Hint:** Restart service to activate!

<code>
    adminAuth: {
        sessionExpiryTime: 86400,
        type: "credentials",
        users: [{
