What it does

Autenticazione Sicura is an agent skill from ccplugins/awesome-claude-code-plugins. Implementa autenticazione sicura quando un sito/app richiede registrazione, login o account utente. Copre verifica email con codice, autenticazione a due fattori (2FA/TOTP), passkey e chiavi di sicurezza, hashing password, sessioni e recupero account. Trigger - "login", "registrazione", "verifica email", "codice di verifica", "2FA", "doppio fattore", "autenticazione", "passkey", "account utente".

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs. The repository describes itself as: Awesome Claude Code plugins — a curated list of slash commands, subagents, MCP servers, and hooks for Claude Code. The licence is Apache-2.0.

When your agent uses it

  • Codice di verifica

Example prompts

  • “registrazione”
  • “verifica email”
  • “codice di verifica”
  • “/autenticazione-sicura”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Passkey / chiavi di sicurezza (WebAuthn/FIDO2) — resistenti al phishing. Librerie: @simplewebauthn/server (Node), webauthn (Python).
  2. TOTP (Google Authenticator ecc.) — segreto generato server-side, mostrato via QR, verificato con finestra ±1 step. Librerie: otplib, pyotp.
  3. Codice via email — minimo accettabile; SMS solo se richiesto esplicitamente.

What it can do on your machine

Read from SKILL.md and the folder at commit 5bd4f16. 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

    No URLs in SKILL.md.

    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

Autenticazione Sicura loads about 745 tokens when it runs. Until then it costs about 105 tokens; SKILL.md has 328 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~105
When it runs · the whole SKILL.md, loaded when a task matches
~745

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.

description
Implementa autenticazione sicura quando un sito/app richiede registrazione, login o account utente. Copre verifica email con codice, autenticazione a due fattori (2FA/TOTP), passkey e chiavi di sicurezza, hashing password, sessioni e recupero account. Trigger - "login", "registrazione", "verifica email", "codice di verifica", "2FA", "doppio fattore", "autenticazione", "passkey", "account utente".

Autenticazione Sicura

Quando un sito/app prevede account utente, implementare l'autenticazione secondo queste regole. Se l'utente non specifica i dettagli, proporre di default: password + verifica email con codice + 2FA opzionale.

Password

  • Hash con Argon2id (preferito) o bcrypt (cost ≥ 12). MAI MD5/SHA1/SHA256 semplice, mai password in chiaro.
  • Lunghezza minima 8-12 caratteri; verificare contro liste di password compromesse se possibile.
  • Rate limiting sul login: max ~5 tentativi per account/IP in 15 minuti, poi blocco temporaneo crescente. Risposta identica per "utente inesistente" e "password errata".

Verifica email con codice (OTP)

  • Codice numerico a 6 cifre generato con CSPRNG (crypto.randomInt, secrets.randbelow), MAI Math.random().
  • Validità 10 minuti, monouso, max 5 tentativi di inserimento, poi invalidare e rigenerare.
  • Salvare nel DB solo l'hash del codice, con scadenza. Rate limiting sull'invio (max 1 ogni 60s, 5/ora per indirizzo).
  • Stesso schema per: conferma registrazione, reset password, conferma di azioni sensibili (cambio email, cambio IBAN, cancellazione account).

2FA / doppio fattore

Offrire in ordine di preferenza:

  1. Passkey / chiavi di sicurezza (WebAuthn/FIDO2) — resistenti al phishing. Librerie: @simplewebauthn/server (Node), webauthn (Python).
  2. TOTP (Google Authenticator ecc.) — segreto generato server-side, mostrato via QR, verificato con finestra ±1 step. Librerie: otplib, pyotp.
  3. Codice via email — minimo accettabile; SMS solo se richiesto esplicitamente.

Regole:

  • Alla attivazione del 2FA generare 10 codici di recupero monouso (mostrati una sola volta, salvati hashati).
  • Richiedere il 2FA a ogni login da dispositivo nuovo e per azioni sensibili (step-up).
  • Disattivazione 2FA solo con ri-autenticazione completa.

Sessioni e token

  • Vedi skill hardening-siti per i cookie. In più: invalidare tutte le sessioni al cambio password; lista "dispositivi connessi" con revoca.
  • Se si usano JWT: scadenza breve (15 min) + refresh token revocabile salvato server-side; algoritmo fissato (no alg: none).

Recupero account

  • Reset password tramite link/codice monouso a scadenza, MAI domande di sicurezza.
  • Notificare via email ogni evento sensibile: login da nuovo dispositivo, cambio password/email, attivazione/disattivazione 2FA.

Cosa non fare mai

  • Inviare password via email. Loggare password o codici OTP. Rivelare se un'email è registrata (enumerazione). Implementare crittografia "fatta in casa".
