Allowed domains is a security function in Nile that is used for multiple different functions as described below:

- [Adding an administrator](https://docs.nilesecure.com/setup-administrators):
  - By default, if "john\@acme.com" has signed up for the Nile Portal, then John can add any other email that belongs to the domain "acme.com" as an administrator to the Nile Portal.
  - But there will be cases, where the customer might have on-boarded a contractor or a consultant to work on behalf of them, in these cases,<u> we need to allow the domain first in order to add the email as an administrator</u>.
- Guest Email approvals:
  - When configuring a captive portal for the guest segment or SSID, if the user selects the authentication method as email approval instead of click-through, the approvers email that a user enters should be from one of the allowed domains.

To add a new allowed domain on the Nile Portal, please navigate to Account Management >> Domains >> Add Domain

Once you have added the domain, you can start [adding administrators](https://docs.nilesecure.com/setup-administrators) & [Installers](https://partnerdocs.nilesecure.com/steps-to-add-an-installer) belonging to that domain.
