A module for managing login and register pages?

[Manaus]

Hello, does it exist a module for managing login and register pages? 

Or do I need to write the logic myself?

Thank you very much

There's LoginRegisterPro: https://processwire.com/store/login-register-pro/

And the older, free LoginRegister: https://github.com/ryancramerdesign/LoginRegister

You can also roll your own, a simple login handler might look like this:

<?php namespace ProcessWire;

http_response_code(400);
header('content-type: text/plain');

$username = input()->post->selectorValue('username');
$potentialUsers = users()->find("roles=my-user, name|email={$username}");

if ($potentialUsers->count != 1)
    die('Uh-oh.');

try
{
    if (!session()->login($potentialUsers->first(), input()->post->pass))
        die("Username or password invalid.");
}
catch (SessionLoginThrottleException $e)
{
    http_response_code(429);
    die($e->getMessage());
}

http_response_code(200);
header('HX-Redirect: '. pages()->request()->getRequestPath());
die('Hello.');
