Bypass Log In Screen at Boot Up

Hello again. I have Volumio installed and working on a USB flash drive. Every time I boot into Volumio a log in screen appears instead of going right to the UI. If I enter volumio for user name and password from the log in screen I get to the command line. If I wait long enough at the log in screen it will go to the UI but I wonder if there’s a way to bypass the log in screen and go right the the UI at boot up. Thanks
