SMS Settings

You need a Twilio account and SMS-capable sender before using SMS authentication.

Account SID

Enter the Account SID from your Twilio account.

Twilio Account SIDs normally begin with AC.

Auth Token

Enter the Auth Token associated with your Twilio account.

HMDIA treats this as a secret. The token is encrypted before it is stored and is not displayed again after saving.

If a token has already been saved, you only need to enter a new one when you want to replace it.

From

Enter the Twilio sender that should be used to send verification codes.

This can be:

• A Twilio phone number in international format, such as +12025550123
• An approved Twilio alphanumeric Sender ID where supported

The sender must be valid for your Twilio account and the countries where you send messages.

Test Connection

After entering your Account SID, Auth Token, and From sender, click Test connection.

HMDIA checks the Twilio connection and validates the sender configuration.

The connection test does not send an SMS, so it does not create a billable message.

A successful test displays:

Twilio connection verified. The sender format is valid.
