[Parody]

Hero Lab Online will log you out when you log in on another session, if you've entered a different Device Nickname on each device+browser combination. (That's what it's asking you to do with the "Wrong device name" error.)

For example, I might have "ParodyComp Vivaldi" and "ParodyComp Firefox" on my computer and "ParodyPhone Chrome" on my Android phone. (Each in their respective browsers.)

When you log in on a different device+browser combo, one of the notifications will be "You have reached your device limit, and your least-recently used devices will be automatically logged out soon: (nickname)". When you go back to that machine, you'll get "Your session has expired and you will need to log in again."
