Password Exposed Laravel Package

Product Decisions This Supports

• Security Compliance & Risk Mitigation: Enables proactive password breach detection, aligning with GDPR, CCPA, and other privacy regulations by identifying compromised credentials before they’re exploited.
• User Trust & Retention: Reduces account takeovers and phishing risks, improving user confidence in platform security (e.g., "We block weak/compromised passwords").
• Roadmap Prioritization: Justifies investment in a Password Security Hub (e.g., combining breach checks, entropy analysis, and multi-factor enforcement) vs. building in-house solutions.
• Build vs. Buy: Avoids reinventing wheel for breach detection (vs. integrating APIs like Have I Been Pwned directly). LGPL-3.0 license allows customization if needed.
• Use Cases:
  • Registration/Login Flows: Real-time validation during signup/password changes.
  • Password Reset: Warn users if their old password was exposed.
  • Audit Logs: Flag exposed passwords in breach investigations.
  • Third-Party Integrations: Offer breach checks as an API for partners (e.g., SSO providers).

When to Consider This Package

Adopt if:

• Your app handles user passwords (auth, SSO, or password managers).
• You lack a dedicated breach detection system but need lightweight, PHP-native integration.
• Your team prioritizes open-source compliance (LGPL-3.0) and wants to avoid vendor lock-in.
• You’re using Laravel/PHP and want minimal setup (e.g., no external API rate limits).

Look elsewhere if:

• You need real-time breach data (this package may rely on static datasets; check last update frequency).
• Your stack is non-PHP (e.g., Node.js, Python) or requires a managed service (e.g., Have I Been Pwned API).
• You require enterprise-grade features (e.g., custom breach thresholds, bulk checks, or SIEM integration).
• Your legal team demands proprietary licensing (LGPL-3.0 may require GPL compliance for modified versions).

How to Pitch It (Stakeholders)

For Executives: "This package lets us proactively block compromised passwords—reducing fraud risk and meeting compliance requirements—with minimal dev effort. For ~$0 cost, we get a turnkey solution that could prevent account takeovers (e.g., credential stuffing) and align with privacy laws. It’s a quick win for security posture, with options to scale later if needed."

For Engineering: "Lightweight PHP/Laravel library to check passwords against known breaches (e.g., LinkedIn, Yahoo). Plugs into auth flows with one function call (PasswordExposed::check()). Uses open-source data (update frequency TBD) and avoids API rate limits. Tradeoff: Less real-time than HIBP API, but easier to maintain and customize. Recommend spiking it against our current breach detection (if any) to compare accuracy."

For Security/Compliance: "Adds a layer of defense against credential stuffing by validating passwords against a breach database. Supports GDPR ‘right to erasure’ by identifying exposed credentials. Note: LGPL-3.0 license requires reviewing modified code for GPL compliance if we fork it."
