How to change routes and database columns in authorization module?

Question

Laravel

Good day to all! I recently started working with Laravel, namely with Laravel 7.x. While I understand the framework, I simultaneously develop a project on it, a project that I initially write on a self-written, so to speak, core similar to Laravel. Now the question arose about authorization, registration and recovery. Please tell me in which classes I need to change the database columns, routes and the rest that is needed? I’m literally doing this right now, and while I’m doing it, I began to doubt that it would work.

Now the file with my routes looks like this:

Auth::routes();

Route::domain(config('app.server_host'))->group(function () {
    Route::get('/', '[email protected]')->name('main-index');
    Route::get('/faq', '[email protected]')->name('main-faq');
    Route::get('/rules', '[email protected]')->name('main-rules');
    Route::get('/rules/game', '[email protected]')->name('main-rules-game');
    Route::get('/rules/network', '[email protected]')->name('main-rules-network');
    Route::get('/rules/terms', '[email protected]')->name('main-rules-terms');
    Route::get('/rules/privacy', '[email protected]')->name('main-rules-privacy');
    Route::get('/phpinfo', function () {
        return phpinfo();
    });
});
Route::domain('xid.' . config('app.server_host'))->group(function () {
    Route::get('/', '[email protected]')->name('xid-index');
    Route::get('/register', 'Auth/[email protected]')->name('xid-create');
    Route::get('/login', 'Auth/[email protected]')->name('xid-login');
    Route::get('/login/recovery', 'Auth/[email protected]')->name('xid-login-recovery');
    Route::get('/phpinfo', function () {
        return phpinfo();
    });
});

Everything else I edited in /vedor/laravel/ui/auth-backend/*. But is it correct?...

Thank you in advance!
