It will first ask for the factory password which is "gosovransystems"
Then, it will ask you for you new password in a pop window titled "Please Type In A New Sovran Pro Updater Password" Once you have thought of your new password and typed it in, make SURE YOU KEEP THIS PASSWORD SAFE and do NOT store it on the Sovran Pro.
Then, it will ask you to type the NEW password again in a new pop up.
That is it!
Now just wait for all the internal passwords to be reset.
When it is finished, a final pop up will state "All Done! All Passwords Are Reset."
