Cannot turn off 2FA

I want to remove 2FA. I uninstalled the app and deselected the checkbox under Settigns -> Security and saved. But still when I try to login from another device it asks for 2FA and says there is no app installed. I want to completely remove 2FA.

Have you tried to use the command line tool to disable the function?!

./occ twofactorauth

  Command "twofactorauth" is not defined.

  Did you mean one of these?
      twofactorauth:admin:generate-code
      twofactorauth:cleanup                       # <<<
      twofactorauth:disable                       # <<<
      twofactorauth:enable
      twofactorauth:enforce
      twofactorauth:gateway:configure
      twofactorauth:gateway:status
      twofactorauth:gateway:test
      twofactorauth:state
