- emailLogin.request / verifyLink / verifyCode / peekLink behind features.emailLogin: one attempt carries a hashed link token and an HMAC'd 6-digit code, consumed once atomically; uniform request response; per email+IP, IP and email rate limits; account created on first verify with a VERIFIED email and a retried generated username. - requiresDeviceStep / runDeviceStep: one 2FA gate for password, email login, magic link and OAuth, with second-step guess limits. - beforeSessionMint hook at every mint site; DEACTIVATED/BANNED refused everywhere, including magic link and passkey. - verifyMagicLink is single-use atomically. - Password reset accepts an app key. - Wildcard-safe case-insensitive lookups (same fix as the 0.20.6 patch).

Minor release for
@factiii/auth(and@factiii/stack).Email sign-in (
features.emailLogin)auth.emailLogin.request/verifyLink/verifyCode/peekLink. One attempt carries a hashed link token and an HMAC'd 6-digit code, consumed once atomically.requestanswers the same for every address; per email+IP, IP and email rate limits; the send never changes the response.appis a key into server config (own keys only); link hosts come only from config.peekLinkreturns a masked address for the confirm screen and spends nothing.appkey.One 2FA gate
requiresDeviceStep/runDeviceStepapply the factor-class rule to password login, email login, magic link and OAuth, with second-step guess limits and the credential spent before any push.hooks.beforeSessionMintruns at every mint site (password, email, magic link, OAuth before linking, passkey). DEACTIVATED and BANNED are refused everywhere.verifyMagicLinkis single-use atomically.Rebased onto 0.20.6; the wildcard-safe lookups from #46 are unchanged in behaviour.
Independently security-reviewed; the findings are fixed in this branch. Tests: 280/280; check-types, lint and build clean.
