How to turn off logging in Usermanager?

If you mean 'Turn off logging' by Authorization Logins and failures every time a user attempts to login, then goto: Routers, click on your Router name, dropdown Main and uncheck whatever Log Events you want disabled. I tend to log Auth Failures for security and troubleshooting purposes, as an auth success usually means they figured it out. But to each their own. This will stop logging to the Logs tab. Granted it will still show up in Sessions as a mgmnt feature but shouldn't log anymore.
