Laravel Password validation Regex (Contain at least one uppercase/lowercase letters and one number)

passwordValidation.php

<?php
/*
* Place this with the rest of your rules.
* Doesn't need to be in an array as there are no pipes.
* Password is required with a minimum of 6 characters
* Should have at least 1 lowercase AND 1 uppercase AND 1 number
*/
$rules = [
    'password' => 'required|min:6|regex:/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d).+$/'
];

/*
* Use this one if you also require at least one symbol.
* Needs to be in an array as it contains a pipe symbol.
* Password is required with a minimum of 6 characters
* Should have at least 1 lowercase AND 1 uppercase AND 1 number AND 1 symbol
*/
$rules = [
    'password' => [
        'required',
        'min:6',
        'regex:/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*(_|[^\w])).+$/'
    ]
];

Thanks!

Thank you very much

Thank You

Thank you

Thanks.

Great ! Easy and crisp 🍡

Adding some more goodies -

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Validator;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        // Register custom validators
        Validator::extend('current_password', function ($attribute, $value, $parameters, $validator) {
            return \Illuminate\Support\Facades\Hash::check($value, auth()->user()->password);
        }, "The :attribute field does not match with your current password.");

        Validator::extend('strong_password', function ($attribute, $value, $parameters, $validator) {
            // Contain at least one uppercase/lowercase letters, one number and one special char
            return preg_match('/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*(_|[^\w])).+$/', (string)$value);
        }, 'Please make a strong password');

    }
}

Thanks

How to apply this validation to ResetPassword also?

You can override the rules trait by doing something like

    protected function rules()
    {
        return [
            'token' => 'required',
            'email' => 'required|email',
            'password' => [
                'required',
                'min:6',
                'regex:/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*(_|[^\w])).+$/'
            ],
        ];
    }

And placing that inside /app/Http/Controllers/Auth/ResetPasswordController.php
