When trying to get the default Laravel Authentication up and running I ran into this error.

'Illuminate\Database\QueryException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter table `users` add unique `users_email_unique`(`email`))'

 

I found this solution to work:

https://laravel-news.com/laravel-5-4-key-too-long-error

 

As outlined in the Migrations guide to fix this all you have to do is edit your AppServiceProvider.php file and inside the boot method set a default string length:

use Illuminate\Support\Facades\Schema;

public function boot()
{
    Schema::defaultStringLength(191);
}

 

You will also need to add this:

use Illuminate\Support\Facades\Schema;
