- How do I install ziming/laravel-zxcvbn in a Laravel app?
- Install it with Composer using composer require ziming/laravel-zxcvbn. Laravel package discovery registers the service provider and facade automatically. Config publishing is optional if you need to adjust package settings. Before rollout, confirm the package version matches your PHP and Laravel constraints.
- Which Laravel versions does ziming/laravel-zxcvbn support?
- The 2.4.6 release adds Laravel 13 support, and the package fits Laravel 10–13 applications needing password-strength validation. If you are on an older Laravel major, pin to a compatible release line and verify constraints in CI. Review the Laravel 13 compatibility change before adopting it because it was contributed by an automated contributor.
- How do I use the zxcvbn validation rule in a Laravel form request?
- Add the package validation rule to your password field in registration, password reset, or profile-update requests. It can replace ad-hoc regex rules or client-side-only strength meters. Run regression tests on all authentication flows after swapping rules. The facade is also available if you need to score passwords directly outside validation.
- What data does the zxcvbn facade return?
- The package exposes zxcvbn-php through a simple facade, returning scores, guesses, crack times, and actionable feedback. That lets you enforce a minimum score while showing users why a password is weak. Use the feedback to improve password guidance instead of only rejecting input. Keep your acceptance threshold aligned with your security policy.
- Is zxcvbn password validation fast enough for high-traffic registration?
- zxcvbn estimation is CPU-bound and runs synchronously in the validation path, so it directly affects request latency. Benchmark p95 latency at expected registration and login volumes before production rollout. At high traffic, consider rate limiting or queueing non-critical strength checks. Profile in staging with representative passwords and concurrency.
- What happens if zxcvbn estimation fails during password validation?
- The provided context does not define a built-in fallback policy, so you should define one explicitly. Decide whether validation fails open or closed when the estimator throws or is misconfigured. Log failures and test the behavior in your auth flows. Document the policy for security and platform teams before rollout.
- Can I customize the zxcvbn configuration in Laravel?
- The package supports optional config publishing, so you can adjust available settings after installation. Review the published config file and package documentation for supported options. Keep customizations minimal and version-controlled. Recheck configuration after Laravel or zxcvbn-php upgrades.
- How do I test Laravel password validation with zxcvbn?
- Write feature tests for registration, password reset, and profile-update flows that submit weak and strong passwords.Assert that weak passwords are rejected with feedback and strong passwords pass your configured threshold. Add failure-path tests for estimator errors if you define fallback behavior. In CI, verify the selected package version against your Laravel and PHP matrix.
- What are alternatives to ziming/laravel-zxcvbn for password strength in Laravel?
- You can use zxcvbn-php directly, build custom entropy or regex rules, or choose another password-strength package. The Laravel wrapper is small and adds a validation rule plus facade over zxcvbn-php. zxcvbn provides realistic scoring and feedback, while simple regex rules are faster but less accurate. Choose based on latency budget, UX requirements, and maintenance ownership.
- Is ziming/laravel-zxcvbn actively maintained and safe for production?
- It is a community-maintained package with no commercial SLA, but recent Dependabot activity and Laravel 13 support suggest it is monitored. Assign ownership to your authentication team and track upstream zxcvbn-php and Laravel major-version support quarterly. Pin versions and review changelogs before upgrades. The wrapper is small enough to fork or vendor if upstream maintenance changes.
