Validation rules for SDK
Frequently asked questions about Validation Rules
- What is twofas/validation-rules and what does it do?
- twofas/validation-rules is a small Composer package from TwoFAS that provides ready-made Laravel validation rules for two-factor authentication flows. It is intended to validate security-sensitive user input such as verification codes and other SDK-related payloads cleanly inside Form Requests, controllers, and custom validators. The package is best treated as a validation primitive rather than a full 2FA implementation.
- How do I install twofas/validation-rules in Laravel?
- Install it with Composer using composer require twofas/validation-rules. Because the package is focused on validation rules, adoption should be a dependency addition plus references to the provided rule classes; it does not appear to require migrations or infrastructure changes. After installation, confirm the autoloaded classes and review the source for the exact rule names and usage.
- Which Laravel and PHP versions does twofas/validation-rules support?
- The supported PHP and Laravel versions are defined in the package composer.json, so check those constraints before installing. Do not assume compatibility with your Laravel major version just because the package is installable. If you are on an older or newer Laravel release, verify whether the rules implement the modern Illuminate\Contracts\Validation\Rule contract or the older string-based approach.
- What validation rules are actually included in twofas/validation-rules?
- The package is described as validation rules for the TwoFAS SDK, but the public context does not enumerate the exact rule classes. Before adopting it, read the source and inventory what it ships, including the accept and reject semantics for each rule. Pay particular attention to rules covering verification codes, TOTP secrets, backup payloads, encryption parameters, or recovery-key formats.
- How do I use twofas/validation-rules in a Laravel Form Request?
- In a Form Request, add the package rule class to the rules array for the relevant field, the same way you would use a custom Rule object. The package is designed for Laravel's validation pipeline, so it should compose with the Validator facade and standard rules. Confirm the constructor arguments and any configuration options by reading the source before wiring it into requests.
- Can I configure the validation rules for different code lengths or alphabets?
- Whether lengths, alphabets, allowed algorithms, or other parameters are configurable depends on how the rules were implemented. The package may encode choices specific to the TwoFAS SDK, so check for constructor parameters or hard-coded assumptions. If your system uses different 2FA formats, you may need to extend the rules or write your own.
- Is twofas/validation-rules safe for production 2FA validation?
- Treat 2FA validation rules as a security control, not just a convenience library. A permissive regex or an off-by-one check in a Base32 or length validation can become an authentication bypass or a lockout. Because this package has little observable community adoption, gate production use on a direct source review and your own negative-case tests.
- Does twofas/validation-rules have tests and CI coverage?
- The provided context does not confirm test coverage or a CI matrix, so verify this in the repository before relying on it. Look for tests covering malformed, oversized, unicode, and boundary-case inputs, not only happy-path codes. If coverage is thin, add your own tests around the exact fields you validate in production.
- Is twofas/validation-rules actively maintained, and what are the alternatives?
- The package appears to be an early-stage or internally extracted library with zero stars and no dependents, so maintenance should be verified through commit history and release cadence. Alternatives include Laravel's built-in validation rules, small custom Rule classes in your App\Rules namespace, or vendoring the specific rules you need. For a security-adjacent domain, owning a small rule can be preferable to taking an opaque dependency.
- Can I copy the rules into my app instead of depending on twofas/validation-rules?
- Yes, vendoring is a realistic option because validation rules are typically small, stateless classes that can live in your own App\Rules namespace. That removes the dependency and lets you adapt the accept and reject semantics to your system. Before copying, confirm the package license is permissive and compatible with your distribution model, and keep attribution as required.
