How to Generate App Key in Laravel 12?

Let's explore how to generate an application key in Laravel 12. This key is essential for encrypting data and ensuring security within your Laravel project.

Laravel provides an encrypted app key in laravel. Every laravel project has its own app key. Based on app key they will generate password, encrypt data etc. so when you get fresh laravel then provide APP_KEY variable on .env file with encrypted value. But when you clone repository from github, gitlab or anywhere then you have to generate new APP_KEY using laravel command.

If you created a .env file and you don't have APP_KEY yet then you will also find "no application encryption key has been specified." error.

So you can generate the app key using the below command:

Then you will see on following .env file with updated value on APP_KEY variable.

.env
