Laravel Auth:attempt() will not persist login

I had this problem. Changing primary key for user model helped for me.

Try to add something like

protected $primaryKey = 'user_id';

in class User{} (app/models/User.php)

(Field user_id is auto increment key in my Schema for 'users' table)

I had the same issue in laravel 5.7. Whoever facing similar issues if session not persisting after authentication , can follow the solution like below..

Open file App\Http\kernel.php

Move \Illuminate\Session\Middleware\StartSession::class, from protected $middlewareGroups to protected $middleware . That's it.

I had this problem today morning, and I realized that when you output data before calling

Auth::attempt($credentials);

Then you can BE SURE THAT YOUR SESSION WILL NOT BE SET.So for example if you do something like

echo "This is the user " . $user;

just above the line that says

Auth::attempt($credentials); 

Then rest assured that you will spend the whole morning trying to find why laravel is not persisting the authenticated user and calling

Auth::user()

will give you a null, and also calling

Auth::check() 

will always give you false.

This was my problem and that is how I fixed it, by removing the echo statement.
