Passcode Lock

Laravel package for passcode (4-digit PIN) lock screen with morph relationship to any model, auto-lock on inactivity, and manual lock via keyboard shortcut.

Requirements

• PHP ^8.5
• Laravel ^12.0|^13.0
• Livewire ^4.2
• xitedev/wireforms ^3.3
• Alpine.js (loaded via Vite)
• Tailwind CSS v4

Designed for projects with Livewire + Wireforms + Alpine.js + Tailwind.

Installation

Publish config (optional, to override defaults):

Implementation

1. Migrations

The package registers create_passcodes_table migration. The passcodes table is created when you run:

Table structure:

• id
• passcodeable_type, passcodeable_id (morph)
• code (hash)
• timeout_minutes (default 10)
• timestamps

2. Model with passcode

Add the HasPasscodeLock trait to the model that should have a passcode (e.g. User or Admin):

Trait methods:

Passcode is 4 digits; hashed via Laravel Hash.

3. Configuration

File config/passcode-lock.php (or published):

• guard — single guard name (e.g. admin, web). Used if guards is not set.
• guards — array of guards for multi-guard passcode lock (e.g. ['admin', 'web']). Overrides guard when set. Session state (last_activity, locked_at) is stored separately per guard; on lock, locked_guard is saved for unlock.
• timeout_minutes — default inactivity timeout (minutes).
• session_keys — session keys for last_activity, locked_at, unlocked_at, locked_guard. With multiple guards, keys (except locked_guard) get a suffix.
• allowed_route_names_when_locked — route names allowed when locked.
• view — lock screen view (default passcode-lock::lock).
• redirect_after_unlock — route after unlock (string or array per guard: ['admin' => 'admin.index', 'web' => 'home']).
• login_route, logout_route — login/logout routes (string or array per guard).

Environment variables (optional):

• PASSCODE_LOCK_GUARD — single guard
• PASSCODE_LOCK_GUARDS — multiple guards, comma-separated, e.g. admin,web
• PASSCODE_TIMEOUT_MINUTES
• PASSCODE_LOCK_IDLE_CHECK_MS — idle check interval in ms (default 30000)

Multiple guards

To use passcode lock for both admin and web user (or other guards):

1. Set guards in config (or PASSCODE_LOCK_GUARDS=admin,web).
2. Models for each guard (e.g. Admin, User) must use the HasPasscodeLock trait.
3. Set redirect_after_unlock and, if needed, login_route as arrays per guard.
4. Middleware detects the current guard; on lock it stores locked_guard, on unlock it uses that guard.

4. Middleware

Add middleware to the web group (e.g. in bootstrap/app.php):

Or via alias:

Middleware:

• Runs only for users of configured guard(s).
• Requires hasPasscodeEnabled() method (i.e. model uses the trait).
• When passcode is enabled: updates last_activity, sets locked_at and redirects on inactivity ≥ timeout.
• Allowed routes when locked — from allowed_route_names_when_locked.

5. Routes

Register package routes (e.g. in routes/web.php):

• lock.show — PIN entry screen.
• lock.unlock — POST with code field (4 digits).
• lock.trigger — instant lock (for idle script and hotkey); must be auth-protected.

6. Lock screen view (Tailwind + Vite)

The package provides view passcode-lock::lock with Tailwind CSS and Vite layout. No color hardcoding — uses Tailwind utilities (primary-*, gray-*), overridable via @theme.

Tailwind content — add package views in resources/css/app.css:

Config options:

Theme — prefers-color-scheme and localStorage.theme.

7. Profile passcode settings (Livewire + Wireforms)

The package provides a Livewire component with Wireforms fields (checkbox, text, button). Add it in your profile card:

Layout must include <x-wireforms::notification/> for success/error messages.

8. Idle and hotkey (Alpine.js)

In the layout where auto-lock and Ctrl+Alt+L manual lock are needed:

The partial registers Alpine component passcodeIdle and renders it only for users with passcode enabled. Config idle_check_interval_ms (env: PASSCODE_LOCK_IDLE_CHECK_MS) — check interval in ms (default 30000).

9. Custom passcode form (without package component)

If not using the package component, call trait methods in your own form:

• Enabled: hasPasscodeEnabled(), disable — setPasscode(null).
• Timeout: setPasscode($code, $timeoutMinutes) or updatePasscodeTimeout($timeoutMinutes).
• New PIN: validate digits:4, confirmed; save — setPasscode($plainCode, $timeoutMinutes).

Translations

The package provides translations in resources/lang/{en,uk}/auth.php and passcode.php (namespace passcode-lock::auth, passcode-lock::passcode). Keys: locked, application_locked, enter_passcode, code, logout, unlock, invalid_passcode, and passcode form labels.

Publish (optional):

Migrating from columns to passcodes table

If passcode was stored in model columns (passcode_enabled, passcode_code, passcode_timeout_minutes), migrate data to the passcodes table and drop those columns. Example migration — in the app repository using this package (e.g. migrate_passcodes_to_package_and_drop_columns).
