Otp Laravel Package

Product Decisions This Supports

• MFA / 2FA roadmap prioritization. TOTP is the lowest-cost, highest-leverage second factor to ship first. This package lets you validate whether "authenticator-app 2FA" is the right initial MFA increment before committing to SMS, push, or passkeys — a cheap spike that de-risks a larger roadmap bet.
• Enterprise / compliance readiness. MFA is a recurring checkbox in security questionnaires (SOC 2, ISO 27001, GDPR-adjacent hardening, many procurement reviews). This package supports the "we can check the 2FA box" conversation and unblocks enterprise deals gated on it.
• Build vs. buy vs. adopt. TOTP is a well-bounded standard (RFC 6238/4226); the real decision is managed MFA vendor vs. self-hosted library. This package is the "self-hosted, minimal, MIT" end of that spectrum — useful when MFA volume is low, when you want no per-seat vendor cost, or when data-residency/legal rules forbid third-party auth processors.
• Scope boundaries for the security surface. Because it does one thing (HOTP/TOTP code generation + verification), it clarifies what you still need to own: secret storage and encryption, replay prevention, recovery codes, rate limiting, enrollment UX, and audit logging.
• Buy vs. extend for adjacent factors. Informs whether passkeys/WebAuthn (a different, larger effort) belongs in the same release or a later one.
• Risk-tiered rollout decisions. Supports deciding to gate 2FA as optional for all users but mandatory for admins, finance, and enterprise tenants first.

When to Consider This Package

Adopt it when most of the following are true:

• Stack fit: You're on PHP/Laravel and want a native library rather than an external auth service or SDK round-trip.
• Scope fit: You need standard TOTP (Google Authenticator, Authy, 1Password, etc.) and nothing more exotic — no push, no SMS, no hardware tokens, no biometrics.
• Compliance posture: Self-hosting is preferred or required (data residency, no third-party PII processor, air-gapped or on-prem deployments).
• Cost sensitivity: You want to avoid per-MAU MFA vendor pricing at a scale where it isn't justified, or you're pre-revenue and want to defer vendor commitment.
• Engineering capacity to own it: You can audit ~a few hundred lines of crypto-adjacent code, pin/vendor the dependency, and accept maintenance responsibility (it's a 5-star, 0-dependent, effectively single-maintainer package — treat it as a source you adopt, not a vendor you rely on).
• Time-to-market matters: You need TOTP working this sprint, not after a procurement cycle.

Look elsewhere when any of these apply:

• You need turnkey MFA breadth (SMS, push, passkeys/WebAuthn, adaptive risk scoring, fraud signals) — evaluate a managed provider (Auth0, Okta, WorkOS, Clerk, Stytch, Twilio Verify) or a broader library.
• You need a supported vendor with an SLA, security review, CVE response commitment, or a named maintainer. This package offers none of those.
• You want community-validated, battle-tested code. More established PHP options exist (e.g., pragmarx/google2fa, spomky-labs/otphp) with larger user bases — worth a bake-off before adopting a 5-star repo.
• Your team lacks the appetite to review cryptographic code or to fork. With zero dependents, there's little external signal that it's been exercised in production at scale.
• You're not on PHP/Laravel. The value proposition evaporates.

Recommended posture if adopted: vendor/fork the source into your repo, pin it, add your own tests around enrollment, drift windows, replay prevention, and recovery-code flows, and document an exit path (the underlying standard means swapping libraries is feasible).

How to Pitch It (Stakeholders)

For executives: We can ship authenticator-app two-factor authentication quickly and at effectively zero licensing cost, using an MIT-licensed library that implements the industry-standard TOTP algorithm. This directly supports security questionnaires and enterprise procurement requirements, and it avoids per-user MFA vendor fees. The trade-off is that we own the maintenance — the package is small and single-maintainer, so we should treat it as code we adopt and review rather than a vendor we depend on. Recommendation: approve a short spike to validate it against a more established alternative before committing.

For engineering: It's a focused, spec-compliant TOTP/HOTP implementation with no external dependencies — small enough to read end-to-end and vendor into the codebase. It handles code generation and verification only; secret storage/encryption, replay protection, rate limiting, recovery codes, and enrollment UX remain ours to build. Because it has minimal community traction, plan to fork, pin, and wrap it behind an internal interface so we can swap in another library (or a managed provider) without touching product code.
