Conversation
…3.8/3.3.9) WCAG 2.2 (W3C Recommendation, Dec 2024) added two success criteria about logging in — 3.3.8 Accessible Authentication (Minimum, AA) and 3.3.9 (Enhanced, AAA) — which forbid relying on a cognitive function test (recalling a password, transcribing a code, solving a puzzle) unless an accessible alternative exists. The spec had no page on this. New page covers supporting password managers, allowing paste, autocomplete="one-time-code", passkeys/WebAuthn, and CAPTCHA alternatives. Status: recommended — it's a new AA criterion in the current WCAG REC, but the web platform does not break without it. - Wires reciprocal relatedSlugs on form-labels, form-errors, mobile-form-inputs, and well-known/webauthn. - Adds the changelog entry and the count-driven + per-page OG images. - SKILL.md left unchanged: it says "130+ pages" (not an exact count), still accurate at 138; category list and tool table unchanged, so no digest bump.

What this changes
Adds a new Accessibility spec page: accessible authentication.
WCAG 2.2 introduced two login-focused success criteria — 3.3.8 Accessible Authentication (Minimum, AA) and 3.3.9 (Enhanced, AAA) — which forbid any authentication step that relies on a cognitive function test (recalling a password, transcribing a code, solving a CAPTCHA) unless an accessible alternative is offered. The page covers supporting password managers (
autocomplete="current-password"), allowing paste everywhere,autocomplete="one-time-code"for OTPs, offering passkeys/WebAuthn, not making a CAPTCHA the only gate, and magic-link fallbacks.recommended,order: 115,appliesTo: [all]autocomplete.Derived/required surfaces included
