How to logout a user from API using laravel Passport

You need to delete the token from the database table oauth_access_tokens you can do that by creating a new model like OauthAccessToken

1. Run the command php artisan make:model OauthAccessToken to create the model.

2. Then create a relation between the User model and the new created OauthAccessToken Model , in User.php add :

   public function AauthAcessToken(){
       return $this->hasMany('\App\OauthAccessToken');
   }
   

3. in UserController.php , create a new function for logout:

   public function logoutApi()
   { 
       if (Auth::check()) {
          Auth::user()->AauthAcessToken()->delete();
       }
   }
   

4. In api.php router , create new route :

    Route::post('logout','UserController@logoutApi');
   

5. Now you can logout by calling posting to URL /api/logout

Make sure that in User model, you have this imported

use Laravel\Passport\HasApiTokens;

and you're using the trait HasApiTokens in the User model class using

use HasApiTokens

inside the user class. Now you create the log out route and in the controller, do this

$user = Auth::user()->token();
$user->revoke();
return 'logged out'; // modify as per your need

This will log the user out from the current device where he requested to log out. If you want to log out from all the devices where he's logged in. Then do this instead

$tokens =  $user->tokens->pluck('id');
Token::whereIn('id', $tokens)
    ->update(['revoked'=> true]);

RefreshToken::whereIn('access_token_id', $tokens)->update(['revoked' => true]);

Make sure to import these two at the top

use Laravel\Passport\RefreshToken;
use Laravel\Passport\Token;

This will revoke all the access and refresh tokens issued to that user. This will log the user out from everywhere. This really comes into help when the user changes his password using reset password or forget password option and you have to log the user out from everywhere.

This is sample code i'm used for log out

public function logout(Request $request)
{
    $request->user()->token()->revoke();
    return response()->json([
        'message' => 'Successfully logged out'
    ]);
}
