Build-an-X workflow for authoring automated tests covering multi-factor authentication flows: TOTP (RFC 6238, deterministic codes from a known secret + fixed time), HOTP (RFC 4226, counter-based), SMS/email OTP, WebAuthn/passkey registration and authentication via Chrome DevTools Protocol virtual authenticator (WebAuthn L2 §11), recovery codes, MFA enrollment, and step-up authentication challenges. Use when the team needs end-to-end MFA test coverage beyond what oauth-flow-test-author covers…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# mfa-flow-test-author ## Overview This skill is the per-flow test recipe for multi-factor authentication. It covers the six second-factor mechanisms most commonly found in production systems. Neighbour skills handle the first-factor and session layers: `oauth-flow-test-author` covers the primary OAuth/OIDC token flow; `session-management-test-author` covers the post-authentication session lifecycle. ## Shared setup All test patterns below require a known, fixed second-factor secret in the test environment. Never use production secrets in tests. Provision per-run secrets using the relevant library and store them in the test fixture. ```python # Common imports used across patterns in this skill import base64, hashlib, hmac, struct, time import pyotp # pyauth.github.io/pyotp ``` ## Step 1 - TOTP (RFC 6238) Per [RFC 6238 §4.2][rfc6238], TOTP = HOTP(K, T) where T = floor((t - T0) / X), T0 = Unix epoch 0 and X = time step (default 30s). TOTP is testable because it is deterministic: a fixed secret + fixed `for_time` always yields the same code. Generate the expected code with `pyotp.TOTP.at(for_time)` ([pyotp][pyotp]) and compare it against what the server accepts. …

How to install
mdr add testland/qa/mfa-flow-test-author@sha256:910e0ccba8a5f3c0The line at the top of this page pins the label v1.2.16, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
