From here the account is protected: the next sign-in asks for the second factor. Third and last of the enrollment calls. Before doing this, make sure the recovery codes have been stored. On success the response has no body (204). Failures: - `400` — the channel was never verified. - `404` — no such user. - `503 IDE-0066` — the identity provider is unavailable (unreachable, too slow to answer, or failing). Nothing about the request was wrong; retry it later. ## OpenAPI ````yaml /pt/openapi/v3-current/AM-identity.yaml post /v1/users/{id}/mfa/enable openapi: 3.1.0 info: contact: name: Lerian Studio url: https://lerian.studio description: OpenAPI 3.1 surface for the Access Manager identity component. license: name: Lerian Studio General License title: Access Manager Identity API version: v1 servers: - url: https://identity.sandbox.lerian.net security: [] tags: - description: >- M2M-only: each plugin declares its own permissions, roles and M2M contract, and the server reconciles them. name: Declarations - description: >- A tenant administrator's customers.
