Set up MessageBird

MessageBird sends SMS one-time codes for this environment.

A newly connected SMS provider becomes the one that sends. Other connected SMS providers stay as fallbacks after a hard failure. With none connected, SMS sign-in and SMS MFA cannot send a code. Authenticator-app MFA does not need MessageBird.

Connect MessageBird

In the Authdog console:

  1. Select the project and environment.
  2. Open Notifications > Providers.
  3. Select the SMS channel.
  4. Choose MessageBird and select Connect.
  5. Enter:
Field Value
Access key A live access key. Stored encrypted. Leave blank on a later edit to keep the stored key
Originator The sender recipients see, for example Authdog, or an E.164 number the account owns
  1. Save. MessageBird becomes the active SMS provider.
  2. Select Test and confirm the message arrives.

The originator is the sender name or number recipients see. Use a key MessageBird will accept for those destinations.

Use it for sign-in or MFA

SMS codes are a channel. Turn the method on separately.

  1. For passwordless sign-in, open Authentication > Methods and enable SMS.
  2. For a second factor, open Authentication and enable Multi-factor authentication, then enroll a test user with SMS before you enforce it.
  3. Sign in and confirm the code arrives from the originator you set.

Connect a test key to development and the live key to production. Providers do not copy between environments.
