Step 1.<\/span><\/strong> Go to config\/app.php<\/span><\/strong> and add <\/p>\n\n\n

Tymon\\JWTAuth\\Providers\\LaravelServiceProvider::class<\/span><\/span><\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\n
 to Providers<\/strong>.<\/p>\n\n\n\n

and add it to your list service providers in app.php<\/strong><\/code><\/p>\n\n\n\n
Step 3.<\/strong><\/span> In your terminal generate the secret: <\/p>\n\n\n
php<\/span> artisan<\/span> jwt<\/span>:secret<\/span><\/code><\/span>Code language:<\/span> CSS<\/span> (<\/span>css<\/span>)<\/span><\/small><\/pre>\n\n\n
Step 4.<\/span><\/strong> In config\/auth.php<\/code> – set the default guard <\/strong>to api<\/strong><\/code>, and change the api<\/code> driver <\/strong>to jwt<\/strong><\/code><\/p>\n\n\n
