There is a web application. You log in to the app and work with it.
Then you take a break.
When you come back after 30 minutes you want to continue, but you can't. There is a popup window which says:
"We have a security measure. When you are logged in to the session and the account is idle for longer than 15 minutes, you have to log in again."
What is the best title for this popup window.
Is re-authentication the best term for this? Or is another term better suited for this?
Thanks alot in advance
