Multiple questions - Guest account

1-Someone can confirm that the guest account type “code” is only limited to 10 devices and same code cannot be provided for large audience?
2- Can we extend the validity period of an already existing guest account?

Answer1: I assume that you are asking if we are able to control the maximum devices connected using the same access code, right? If so the answer is yes, the access code is an account and in the Guest Access Strategy you control how many devices per account are able to connect.

Answer2: Regarding the validity period unfortunately the answer is no, currently the validity period is a global Guest parameter managed from the Guest Access Strategy as well, so any change on this variable will apply to every Guest account and not independently for each account.
