Problem
You want your application’s users in a different table than users.
Your application is using database authentication and needs to use a different table than Laravel’s default users table.
Solution
Edit app/config/auth.php
to change the table.
'table' => 'administrators',
Discussion
Don’t forget the required columns.
Whatever the authentication table is set to, it must contain an id column, a password column, and some other column to authentication the user with. This other column is typically either email or username.
