Laravel Otp Laravel Package

Product Decisions This Supports

• Authentication and verification flows: OTP generation and validation underpins login, signup, password reset, transaction confirmation, and step-up verification. This package is a candidate for any roadmap item that requires a "prove you own this channel" moment.
• Build vs. buy: OTP issuance looks trivial and is not. Correctness hinges on token entropy, expiry windows, rate limiting, single-use enforcement, and safe comparison. Adopting a maintained package lets the team spend its engineering budget on product differentiation rather than on re-deriving security primitives.
• Token format as a product choice: v2.0.0 adds alphanumeric token generation, which is a real UX and cost lever, not just a technical detail. Numeric-only codes are easier to read aloud and type on feature phones; alphanumeric codes raise the effective search space, allowing shorter codes or shorter lifetimes at equivalent risk. This lets you tune the trade-off per channel (SMS vs. email vs. authenticator) instead of accepting a single global format.
• Operational tooling: The improved otp:clean output gives useful information during cleanup runs. That is a small but genuine operations win — it makes expiry hygiene observable, which matters when stale tokens are a compliance or storage concern, and it reduces the guesswork when diagnosing "why did this code stop working" support tickets.
• Architecture and testability: Abolishing Facades in favour of explicit dependency injection is a maintainability decision with downstream product consequences. It makes the package easier to mock and swap behind an interface, which in turn makes it cheaper to migrate providers or add a second channel later without touching call sites.
• Upgrade planning as a roadmap item: The facade removal and the validate() refactor are both potentially breaking. Any team currently on v1.x should treat the upgrade as scheduled work with a regression-testing allocation, not a drive-by composer bump.

When to Consider This Package

Adopt when:

• You are building OTP-based verification in a Laravel application and want the mechanics handled by a focused, single-responsibility dependency rather than bespoke code.
• You need configurable token formats — the new alphanumeric support means one package can serve both low-friction numeric flows and higher-assurance alphanumeric flows.
• Your team values explicitness in the container: the removal of Facades suits codebases that inject services and test with mocks rather than relying on global resolution.
• You want expiry cleanup you can actually observe in logs or CI output, rather than a silent scheduled command.
• You are starting fresh on v2.0.0 and can adopt the current API without a migration.

Look elsewhere or build in-house when:

• You need a full identity platform — multi-factor orchestration, recovery codes, device trust, push approval, WebAuthn. This package addresses OTP generation and validation, not the surrounding identity product.
• Delivery is your real problem. The hard parts of OTP at scale are SMS routing, carrier deliverability, per-number rate limiting, and fraud/abuse detection (SMS pumping, toll fraud). A generation library does not solve those; a managed provider with delivery and risk scoring might.
• You are on v1.x with heavy facade usage and a near-term freeze: the breaking changes make this a deliberate migration, and deferring may be the right call if the current version is stable and unexposed.
• You require vendor-backed SLAs, audited compliance attestations, or formal security review — an open-source package shifts that assurance burden onto your own review process.
• Your threat model needs hardware tokens or cryptographic challenge-response rather than shared-secret codes.

Before committing, verify: the migration guide for the facade removal and validate() signature changes, the entropy source and comparison method used for alphanumeric tokens, whether rate limiting and attempt-capping are built in or left to the caller, and the test coverage around expiry and replay. Run the upgrade on a branch with the full auth test suite as the gate.

How to Pitch It (Stakeholders)

To executives: This is a small, low-cost dependency that handles one security-sensitive primitive — one-time passcodes — correctly, so our engineers do not hand-roll it. The v2.0.0 release gives us flexibility in how codes look, which lets us make better trade-offs between user friction and fraud risk per channel, and it improves the operational visibility of token cleanup. The cost is a scoped upgrade: two changes are breaking, so we should budget a short migration and regression-testing window rather than absorbing it silently. There is no new licensing or vendor commitment.

To engineering: v2.0.0 adds alphanumeric token generation, removes Facades in favour of container-resolved dependencies, refactors validate(), and makes otp:clean report useful information. Two of those are breaking: any facade calls or Otp:: static usage must move to injection, and validate() call sites need to be checked against the refactor. The direction is good — explicit dependencies improve testability and make the package swappable behind an interface — but the upgrade needs to be a deliberate task against the auth test suite, not a composer update in a feature branch. Pin the version, read the upgrade notes, and treat alphanumeric tokens as a new configuration surface that needs its own expiry and rate-limit decisions rather than a default we inherit.
