2Fa Laravel Package

Product Decisions This Supports

• Feature: 2FA in the login flow. This is table-stakes for B2B SaaS, admin consoles, and any product sold into security-reviewed enterprises. It unblocks deals gated on a security questionnaire rather than creating new revenue on its own — treat it as an unblocker, not a differentiator.
• Build vs. buy: buy the mechanics, own the policy. TOTP secret generation, clock-skew windows, replay protection, single-use backup codes, and trusted-device tokens are exactly the kind of thing that looks like a two-day task and turns into a three-week task plus a permanent security-maintenance line item. The package covers the cryptography and the state machine; your team owns enrollment UX, enforcement policy, and recovery support flows.
• Roadmap sequencing. A defensible sequence is: TOTP for admins and privileged roles → backup codes and recovery → trusted devices to cut support tickets → email codes as a low-friction fallback for non-technical users → custom authenticators (SMS, WebAuthn) only when a specific customer or compliance regime demands it. Each step is a separate commitment; the library does not force you to ship all of it at once.
• Scoping question worth answering early: which framework are we actually on? The core is framework-agnostic, but the first-class integration is a Symfony bundle — this is not a Laravel-native package despite sitting in the PHP ecosystem. On Laravel you would be wiring the core yourself (or comparing against Laravel's own auth scaffolding), which changes the effort estimate materially. Do not let this get scoped as "drop in the package."
• Compliance enablement. If SOC 2, ISO 27001, or customer security reviews are on the roadmap, 2FA is a control you will be asked to evidence. Choosing a library with thorough tests and a documented extension point makes that evidence conversation shorter.
• Support-cost modeling. Trusted devices and backup codes are the two features that most directly reduce "I lost my phone" tickets. Their presence here is worth more in the business case than the authenticator list.

When to Consider This Package

Consider it when:

• The application is Symfony-based, where the bundle gives you a genuinely low-friction integration against your existing user provider.
• You are on another PHP framework but are comfortable owning the glue: the core is framework-agnostic, so the work is integration and session handling rather than cryptography.
• You need TOTP, email codes, and backup codes as the first release, with a credible path to SMS or hardware keys via a small custom authenticator interface.
• You want trusted devices without designing device-token storage and expiry yourself.
• You need to hook into preparation and validation to express policy — e.g. enforce 2FA for a role, or allow a grace period after enrollment.
• You value a maintained dependency: MIT-licensed, actively released, documented, tested.

Look elsewhere when:

• You are on Laravel and expect a native, batteries-included integration. The integration work is yours; price it accordingly, and compare honestly against Laravel's own auth/2FA tooling and well-known TOTP packages before committing.
• WebAuthn/passkeys are a near-term requirement. They are not in the box; you would build a custom authenticator, so evaluate whether a passkey-first identity provider is the better bet.
• SMS delivery is a hard requirement at launch — that is a custom authenticator plus a vendor decision, not an out-of-box capability.
• You want zero ownership of the auth surface. A managed identity provider (Auth0, Cognito, WorkOS, and similar) trades per-user cost and lock-in for removing this from your on-call rotation. For a small team without security depth, that trade is often correct.
• You need a large, active community as a risk hedge. Adoption here is real but modest (~595 stars) — it is a mature niche library, not a movement. That is fine for a well-tested auth primitive, but it should be a conscious acceptance, not an assumption.

How to Pitch It (Stakeholders)

For executives: Two-factor authentication is a checkbox on nearly every enterprise security review we will face, and its absence is a recurring reason deals stall late. This library lets us add it in days rather than weeks, without inventing security-critical code in-house. Cost is negligible; the real cost is the integration and the enrollment UX, and the risk is concentrated in a single maintained dependency rather than spread across our own crypto.

For engineering: A tested, MIT-licensed implementation of the hard parts — TOTP verification with clock-skew handling, single-use backup codes, trusted-device tokens, and a pluggable authenticator interface for anything we add later. On Symfony it is close to drop-in; on Laravel we own the wiring and should estimate it as a small integration project, not a dependency install. We keep control of enforcement policy and the user-facing flow; the library owns the mechanics.

The honest caveats to state up front: this is not a Laravel-native package despite being PHP, passkeys and SMS require custom work, and the community is modest — so we are betting on a well-maintained niche library for a security primitive. That bet is reasonable given the test coverage and documentation, but it is a bet, and someone should own watching its release cadence.
