SMS code is passwordless sign-in: a one-time code sent to the user's phone. The method does nothing until the same environment has an SMS provider connected. Authenticator-app MFA is a separate setting and does not use this method.
Connect a provider first
In the Authdog console, select the project and environment, open Notifications > Providers, and select the SMS channel. Connect one provider and send its test:
The provider you just connected becomes the one that sends. Others you connect later are fallbacks after a hard failure.
Enable the method
- Open Authentication > Methods.
- Enable SMS.
- Open the hosted sign-in page for that environment.
- Request a code for a handset you control and enter it.
- Confirm the user session is created.
If the test from the provider succeeds and the sign-in code never arrives, the method is on but the active provider is a different environment's. Providers do not copy between environments.
SMS as a second factor, after a password or social sign-in, is configured under Multi-factor authentication, not by this method. See Multi-factor authentication.
