Send your MFA code through any channel with the custom factor

The new custom factor for multi-factor authentication removes the channel limit. Appwrite generates and verifies a 6-digit code, and your application decides how the user receives it: WhatsApp, a voice call, an internal messaging system, or any provider that Appwrite does not support directly.

Create a challenge with the custom factor, then read the code with a Server SDK, or from an Appwrite Function that holds the users.read scope. Appwrite delivers nothing for this factor, so your application sends the code through your own channel. The user then completes the challenge in the same way as every other factor.
