Development_AdminBypass

⚠️ FOR LOCAL DEVELOPMENT ONLY — NEVER ENABLE IN PRODUCTION

Bypasses Magento 2 admin authentication and auto-logs in a hardcoded development user (local / local123) whenever the admin login page is visited.

What it does

BypassAdminAuthentication (plugin around on Magento\User\Model\User::verifyIdentity) — accepts any password for any existing admin user.
AdminAutologin (plugin around on Magento\Backend\Controller\Adminhtml\Auth\Login::execute) — when /admin is visited and nobody is logged in, creates the admin user local (password local123, email john.smith@gmail.com, role Administrators) if missing and authenticates as that user. Redirects to */dashboard.

Safety model

This module is guarded by Magento's application mode:

Mode	`Allow in Production` flag	Behavior
`developer` / `default`	any	active — bypass and autologin work
`production`	`No` (default)	inactive — Magento behaves normally, no user is created
`production`	`Yes`	active — explicit override (use at your own risk)

The guard is implemented in Development_Core (Development\Core\Model\ProductionGuard::isEnabled()) and wired into every plugin via a virtualType in etc/di.xml that binds it to the config path development/admin_bypass/allow_in_production. In production + flag off, the plugins short-circuit with $proceed(...) and do not create the local user nor touch authentication.

Configuration

Panel path: Stores → Configuration → ⚠ Development Modules → Admin Bypass → General → Allow in Production

Default: No.
Changing this flag requires bin/magento cache:clean config to take effect.

Install

composer require --dev jeanmarcos/module-admin-bypass
bin/magento module:enable Development_AdminBypass
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento cache:flush

Kill switch (strongly recommended before any deploy)

bin/magento module:disable Development_AdminBypass
bin/magento setup:upgrade
bin/magento cache:flush

The disable path is the last line of defense — it removes the module entirely regardless of the allow_in_production flag.

For permanent removal:

composer remove jeanmarcos/module-admin-bypass

Security risks (read before using)

Anyone who can reach /admin gains full Administrators access when the bypass is active. No password needed.
The hardcoded local/local123 admin user persists in the database once created, even after disabling the module.
Credentials are in plain text in Plugin/AdminAutologin.php and are searchable in git history.

After disabling the module in a shared environment, consider deleting the local admin user manually:

DELETE FROM admin_user WHERE username = 'local';

The production-guard helper lives in the shared core package jeanmarcos/module-core-local-development.

Troubleshooting

Toggle doesn't take effect: bin/magento cache:clean config.
Bypass still works after module:disable: check app/etc/config.php for the module entry; run setup:upgrade.
Autologin loops: another plugin on Login::execute may be conflicting; inspect generated/code/Magento/Backend/Controller/Adminhtml/Auth/Login/Interceptor.php.

Compatibility

Magento 2.4.x
PHP 8.1+ (uses constructor property promotion and readonly properties)
Depends on jeanmarcos/module-core-local-development (installed automatically by Composer).
