# Security Updates to Messaging API & Portal

### 18, Mar 2024

In order to improve the security of Telnyx’s Messaging platform for end users, we have implemented two changes to Messaging Profiles:

1. Editing / Creating a Messaging or Verify Profile via the Portal and API will require users to configure whitelisted destination countries for outbound termination. Note that existing profiles will not be affected - only those that are newly edited or created.
2. When attempting to send to non-US destinations, Telnyx now requires a default Alphanumeric sender ID to be named on the Messaging Profile.

### Further information:

1. To learn about setting up Messaging Profiles, refer to [this article](https://support.telnyx.com/en/articles/3562059-setting-up-a-messaging-profile).
2. You can configure a Alphanumeric Sender ID on the messaging profile via the [Portal](https://portal.telnyx.com) or [API](https://developers.telnyx.com/api/messaging/create-messaging-profile).
