Security and Accessibility: No Tradeoff Required

Security is mostly backend; accessibility is mostly frontend

Real security: encryption (TLS/SSL), authentication tokens, rate limiting, input validation. All backend. Frontend UI can be fully accessible. Confusing frontend security theater with backend security is mistake.

CAPTCHA blocks disabled users; isn't real security

CAPTCHA (visual puzzle) fails for blind users. CAPTCHA isn't reliable (bots solve them; users fail them). WCAG 2.2 bans CAPTCHA-only auth. Use: email verification, SMS code, security questions, biometric. Better security AND accessibility.

Authentication can have multiple methods

Don't force single auth method. Password + biometric + SMS code + security questions = secure for all users. Single method (password only, SMS only, fingerprint only) excludes users.

Keyboard traps are security theater

Some sites use keyboard traps (Escape key disabled, Tab loops) as 'security'. This breaks accessibility without improving security. Keyboard traps don't prevent fraud; they block disabled users.

Users with disabilities aren't higher risk

False assumption: disabled users are less trustworthy. Untrue. Provide same security/accessibility to all users. Accommodations (screen readers, voice control, mobility devices) don't reduce security if backend is strong.

Audit security assumptions: which 'security' features are actually frontend theater? Move to backend.

Kill CAPTCHAs: implement email verification, SMS codes, security questions, biometric. Better security + accessibility.

Implement multiple auth methods: password + backup options. Users choose what works for them.

Ensure keyboard navigation: all auth flows keyboard accessible. Test with Escape, Tab, Enter only.

Backend encryption: ensure TLS/SSL, token validation, rate limiting. Don't rely on UI for security.

Test authentication with assistive tech: can users with screen readers complete login flow?

Document security model: where does real security live (backend). Where is accessibility needed (frontend). Make distinction clear to developers.

Using CAPTCHA as primary auth (blocks disabled users; bad security anyway)

Keyboard trap as 'security' (not secure; breaks accessibility)

Requiring JavaScript for all functionality (breaks users without JS; accessibility issue)

Only SMS code auth (doesn't work for deaf users; no email option)

Assuming security audit = accessibility audit (separate skills; need both)

Building complex UI 'security' logic (belongs in backend, not UI)

Disabling paste in password field 'for security' (actually hurts password managers; breaks accessibility)
