2. Open a terminal
3. Once the command prompt appears, type ssh your.UserName@lawrence.usd.edu
   Note: Your username is often your first (given) name, a period (.), and your last name (surname) with no spaces (e.g., ssh Charlie.Coyote@lawrence.usd.edu)
4. When the password prompt appears, type your password
   Note: When passwords are typed in a bash shell, the cursor doesn't move or blink
5. Complete your Duo second authentication method
   1. You must approve the Push on your mobile device
   2. OR You must type in the six-digit passcode from the Duo token (ie. 123456) and press enter
6. If login is successful, a welcome message and new command prompt will appear
   Note: if you mistyped your password, the system will send you back to step 4
