How to make authorization for applications on laravel Passport?

Question

User identification

How to authorize external users on Laravel in the application i.e. give them a Personal Access Token?
At the moment it is implemented as follows.
There is a standard route /oauth/token. The following parameters are passed to it via a post request:
1) grant_type = 'password'
2) client_id from the oauth_clients table, Laravel Password Grant Client user id
3) client_secret = from the oauth_clients table, secret of the Laravel Password Grant Client user
4) username = user login
5 ) password = user password
as a result of the response, we get the data we need (token).
This method requires stitching data 2 and 3 into the application, I'm not sure if this is a good idea.
Alternatively, you can write a method that will issue a token using $user->createToken('mobile1')->accessToken, but this idea seems to me not the best.
Therefore, the question is how to issue an authorization token to the application user as correctly as possible?
