How does Laravel: display the key? of Passport

https://laravel.com/docs/5.7/.

after running php artisan passport:keys , I generate client_id and client_secret , but accidentally close the command line window, so what command is used to check the generated client_id and client_secret ?

I also use 5.3 . Looking at the command introduction, the high probability is .env

.
When deploying Passport to your production servers for the first time, 
you will likely need to run the passport:keys command.
This command generates the encryption keys Passport needs in order to generate access token. 
The generated keys are not typically kept in source control
