Laravel Breeze Auth: Login With Email Or Username Example

In this post, I will show you how to login with email or username with laravel breeze authentication.

Sometimes, we may need to let users log in using either their email or username. How can you achieve this if you've implemented the Laravel breeze authentication scaffold?

I'll walk you through a simple solution that allows users to log in with either their email or username.

we simply go to LoginRequest.php request file and overwrite authenticate() method with the following code:

App/Http/Requests/Auth/LoginRequest.php

<?php

namespace App\Http\Requests\Auth;

use Illuminate\Auth\Events\Lockout;
use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Support\Str;
use Illuminate\Validation\ValidationException;

class LoginRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     */
    public function authorize(): bool
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules(): array
    {
        return [
            'login' => ['required', 'string'],
            'password' => ['required', 'string'],
        ];
    }

    /**
     * Attempt to authenticate the request's credentials.
     *
     * @throws \Illuminate\Validation\ValidationException
     */
    public function authenticate(): void
    {
        $this->ensureIsNotRateLimited();

        $login_name = filter_var($this->input("login"), FILTER_VALIDATE_EMAIL) ? "email" : "username";

        $this->merge([
            $login_name => $this->input("login")
        ]);

        if (! Auth::attempt($this->only($login_name, 'password'), $this->boolean('remember'))) {
            RateLimiter::hit($this->throttleKey());

            throw ValidationException::withMessages([
                'login' => trans('auth.failed'),
            ]);
        }

        RateLimiter::clear($this->throttleKey());
    }

    /**
     * Ensure the login request is not rate limited.
     *
     * @throws \Illuminate\Validation\ValidationException
     */
    public function ensureIsNotRateLimited(): void
    {
        if (! RateLimiter::tooManyAttempts($this->throttleKey(), 5)) {
            return;
        }

        event(new Lockout($this));

        $seconds = RateLimiter::availableIn($this->throttleKey());

        throw ValidationException::withMessages([
            'email' => trans('auth.throttle', [
                'seconds' => $seconds,
                'minutes' => ceil($seconds / 60),
            ]),
        ]);
    }

    /**
     * Get the rate limiting throttle key for the request.
     */
    public function throttleKey(): string
    {
        return Str::transliterate(Str::lower($this->string('email')).'|'.$this->ip());
    }
}
