At a glance

Reviews sign-in, MFA, CAPTCHA and recovery flows for accessibility barriers such as blocked paste, memorized codes and transcription, and suggests fixes.

  • Reviewing a login, sign-up or MFA flow for accessibility
  • SKILL.md covers Quick Reference, Check, Fix and Explain, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Auditing password reset and account recovery steps

What it does

The skill treats login as a common first blocker for users with cognitive, motor, low-vision or speech-input needs. It works in four modes: check a flow for problems, fix them, explain the WCAG Accessible Authentication principle, or review code for the exact steps that demand memorization or transcription.

Its quick reference says not to block paste or password managers, to prefer passkeys, magic links or device approval, to support one-time code autofill with autocomplete=one-time-code, and to avoid CAPTCHA or knowledge checks that have no alternative. It asks for at least one sign-in path that does not rely on a cognitive function test, and sends you to references/rule.md for code examples and framework-specific guidance.

When your agent uses it

  • Reviewing a login, sign-up or MFA flow for accessibility
  • Auditing password reset and account recovery steps
  • Replacing a CAPTCHA that has no accessible alternative
  • Fixing one-time code inputs so paste and autofill work

Example prompts

  • “Audit our login and password reset pages for accessible authentication problems.”
  • “Make the OTP field accept paste and autofill.”
  • “Explain why blocking paste on the password field fails WCAG Accessible Authentication.”
  • “Review the MFA step in this pull request for transcription barriers.”

What it can do on your machine

Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • frontendchecklist.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Accessible Authentication Review loads about 579 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 226 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~579
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Provide accessible authentication methods

Authentication often becomes the first hard blocker for users with cognitive, motor, low-vision, or speech-input needs. If sign-in, MFA, or recovery relies on memorization or transcription with no assisted path, the user may be locked out before they can access the product at all.

Quick Reference

  • Do not block paste or password managers in login and recovery flows
  • Prefer passkeys, magic links, device approval, or password-manager-friendly flows
  • Support OTP autofill and paste with appropriate semantics such as autocomplete="one-time-code"
  • Avoid CAPTCHA or secondary checks that require memorizing or transcribing information without an alternative

Check

Review login, MFA, password reset, and account recovery for accessible authentication problems. Flag blocked paste, password-manager hostility, manual transcription requirements, inaccessible OTP handling, and CAPTCHA or knowledge checks without a compliant alternative.

Fix

Add password-manager-friendly fields, support paste and OTP autofill, and provide at least one authentication path that does not depend on a cognitive function test.

Explain

Explain WCAG Accessible Authentication, why memorization and transcription are barriers, and how passkeys, password managers, OTP autofill, and device approval improve both accessibility and security.

Code Review

Review authentication pages, MFA steps, recovery flows, and security controls related to Provide accessible authentication methods. Flag exact steps that require memorization, transcription, blocked assistive tooling, or inaccessible fallback paths.
