Laravel 6: Call to Undefined Method App\\User::Createtoken()

Call to undefined method App\Models\User::createToken()

the method createToken is in HasApiTokens trait, you should use it In your User Model
:

 use Laravel\Passport\HasApiTokens;

  class User extends Authenticatable
    {
    use HasApiTokens;
    }

Laravel 6: Call to undefined method App\\User::createToken()

Since your guard is returning the wrong User model, App\User, you should check your auth configuration, 'config/auth.php'. In the providers array adjust any provider, usually users, that is using the App\User model to App\Models\User instead.

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        // 'model' => App\User::class,
        'model' => App\Models\User::class,
    ],
    ...
],

Call to undefined method App\Models\StudentModel::createToken()

You need to use the HasApiTokens trait that you imported on your User Model:

class StudentModel extends Authenticatable 
{
    use HasFactory, Notifiable, HasApiTokens;
    //...
}

Laravel 8: undefined method 'createToken' intelephense(1013)

I encountered the same problem and solved by adding the line. For my case.

    /** @var \App\Models\MyUserModel $user **/
    $user = Auth::user();

I think the annotation line tell PHP intelephense that $user variable is not Illuminate\Foundation\Auth\User type but \App\Models\MyUserModel type. Please try it.

Call to undefined method Laravel\Socialite\Two\User::createToken()

First of all the problem I was having with having a token generated by passport for users authentication after the first social login was because I was calling the createToken method on the user returned by Socialite. As explained by @JorisJ1 Socialite does not have the createToken function so my initial code threw an error.

Here's how I fixed it

public function handleProviderCallback($provider)
{
    // retrieve social user info
    $socialUser = Socialite::driver($provider)->stateless()->user();

    // check if social user provider record is stored
    $userSocialAccount = SocialAccount::where('provider_id', $socialUser->id)->where('provider_name', $provider)->first();

    if ($userSocialAccount) {

        // retrieve the user from users store
        $user = User::find($userSocialAccount->user_id);

        // assign access token to user
        $token = $user->createToken('Pramopro')->accessToken;

        // return access token & user data
        return response()->json([
            'token' => $token,
            'user'  => (new UserResource($user))
        ]);
    } else {
        ...
    }
}

Comments are welcomed if there is a better way for adding social authentication to API.

Call to undefined method Illuminate\Database\Query\Builder::withAccessToken()

i solved this by adding "use HasApiTokens, Notifiable;" in App/User.php

I get BadMethodCallException Call to undefined method App\Models\User::identifiableAttribute()

your have forgotten to use 'CrudTrait' in your User Model:

use Backpack\CRUD\app\Models\Traits\CrudTrait;

class User extends Authenticatable
{
  use Notifiable,CrudTrait
    .......
 }
