php – How to use Laravel Passport with a custom username column

Posted by: admin April 23, 2020 Leave a comment

Questions:

Now I’m using something like that for authenticating the user on my base site:

if (Auth::attempt($request->only(['id', 'password']))) {
            //
}

How can I modify this code for using custom column as username?
https://laravel.com/docs/5.3/passport#password-grant-tokens

How to&Answers:

You can use findForPassport method in your user model.

This method take username as argument, and return user model

For example:

class User extends Authenticatable
{
    use HasApiTokens, Notifiable;

    // ... some code

    public function findForPassport($username) {
        return $this->where('id', $username)->first();
    }
}

Answer:

A bit too late to answer, but I’ve been having a hard time trying to figure this out, so for the sake of completeness and to maybe help others in the future.

If you take a look to this part of passport’s code you’ll see that it also looks for a validateForPassportPasswordGrant method, so in addition to Alexander’s answer, that’s how you can authenticate an user using custom fields.

Hope it helps someone.
