- Is jonasarts/google-authenticator-bundle a Laravel package?
- No. jonasarts/google-authenticator-bundle is a Symfony bundle: it ships a Bundle class, a DI extension, and a Configuration tree that only resolve inside a Symfony kernel. There is no Laravel service provider, facade, or publishable config. If you are building on Laravel, treat it as a TOTP implementation to study or vendor, not a package to require.
- Can I install this Symfony bundle in a Laravel application?
- Not in any working way. Composer may resolve the dependency, but Laravel never registers bundles or merges Symfony extension config, so the package's primary delivery mechanism is inert. You would be rewriting the integration as a service provider around the underlying TOTP class, roughly two to four engineering days including tests, config, and QR provisioning. That is a refactor, not an install.
- What does this bundle actually provide for TOTP two-factor authentication?
- It wraps RFC 6238 TOTP into reusable Symfony services: per-user secret generation, otpauth:// provisioning URIs you can render as QR codes, and verification of six-digit codes with a configurable time-window tolerance. Issuer and account labels are configurable so entries display correctly in Google Authenticator, Authy, and 1Password. The genuinely reusable part is the small TOTP class, not the Symfony wiring.
- What Laravel or PHP alternatives should I use instead of this bundle?
- For Laravel, standardize on pragmarx/google2fa-laravel for a framework-native experience, or spomky-labs/otphp if you want a maintained OTP core and full control over the login flow. Both give you the same secret generation, provisioning URI, and code verification primitives. This bundle's only real differentiator is Symfony service wiring you cannot use in a Laravel app.
- Which Symfony and PHP versions does this bundle support?
- The bundle follows Symfony 4/5-era Flex conventions, so check the composer.json PHP and symfony/* constraints before anything else. A Symfony 4-era constraint set may not declare PHP 8.2+ support, producing a dependency resolution conflict before a single line of code runs. For a Laravel 10 or 11 target on PHP 8.2+, that is usually the first hard stop.
- How do I generate a TOTP secret and provisioning QR code with this bundle?
- Inside Symfony you inject the bundle's services and call them for secret creation and otpauth:// provisioning URIs, then render the URI as a QR code. In Laravel, the practical route is to lift the TOTP class into app/Support/ or a first-party package, wrap it behind a TotpService interface, and bind it in a service provider. Keep the upstream dependency out of composer.json so a dead project cannot block a framework upgrade.
- Does it handle time-window tolerance and replay protection for used codes?
- Time-window tolerance is configurable, which covers ordinary clock drift between your server and the user's phone. Replay protection, meaning rejecting a code that was already accepted, is not documented, so you must store the last accepted timestep or code per user and reject duplicates yourself. Also confirm the implementation compares codes in constant time, for example with hash_equals, rather than using loose string equality.
- How do I test TOTP code validation in a Laravel test suite?
- Pin the clock rather than sleeping: freeze time with Carbon::setTestNow() or an equivalent clock abstraction, generate a code from a known secret at a known timestamp, and assert that verification passes. Add cases for the edge of your drift window, an expired code, a reused code, and malformed or wrong-length input. Never test against real wall-clock time, or the suite will fail intermittently at window boundaries.
- Is the package actively maintained and safe for production authentication?
- Adoption signals are weak: four stars, zero dependents, a composite score near 0.05, and effectively a single maintainer. For an authentication primitive that means no downstream production validation and little community pressure to fix security defects. The MIT license is clean, but check the health, CVE history, and release cadence of the underlying TOTP library, because the wrapper's maintenance is irrelevant if the core is stale.
- How do I migrate from this bundle to a Laravel-native 2FA solution?
- Run a one-day spike: lift the TOTP class into a throwaway Laravel command and verify secret generation, provisioning URI, and code verification against Google Authenticator, Authy, and 1Password. If nothing proprietary surfaces, close the bundle evaluation and adopt a Laravel-native package, recording the rejection rationale so it is not re-proposed next quarter. Run the spike in parallel with your 2FA roadmap so it never blocks delivery.
