Automate Guest Account Expiration

[ProHeatheus]

I have created a guest wireless network that gives 10 minutes of internet access after registration and requires email verification to continue to use the internet. 

Is there a way to set the account to expire automatically based on date/time of creation?

I am able to set the expiration date manually by going to Users > Authorization > Authorize Users > Set Expiration Date. But I would like to automate this process. 

Any ideas? Am I overlooking a setting somewhere?

Many thanks!

Not to make the account expire - only to set the maximum session time.  After that, they are logged out but can log back in again.

You would need to use a third-party service like Splash Access to do this.
