How to Disable Security Loging

Hi all

Now I'm need to disable this function, and this is not work.
So, I need some help with this...How to disable security, after security was enable and have problems with password and loggin...

What have you enabled? If it is just adminAuth then comment out fully the adminAuth section in settings.js and restart node-red.
If it still doesn't work then in a terminal run

node-red-stop
node-red-start

and copy/paste the startup log here, after looking at it carefully to see if it tells you anything useful.
