#1 Basic usage 

echo wp_login_url(); // https://wp-kama.com/wp-login.php
<a href="<?= wp_login_url() ?>" title="Login">Log in</a>
0

#2 Authorize and Redirect to Current Page 

<a href="<?= wp_login_url( get_permalink() ); ?>">Login</a>

Note that if the request is a 404, get_permalink() will return false, so you may want to grab the actual URL instead.

A scenario where it could be useful to still redirect to your current URL even if it was a 404, would be if the current URL was a private post, and your user was not yet logged-in – hence ended up on a 404.

In that case, if you show them a login link, they should be redirected back to the current URL (i.e. the private post), so that they finally can access it.

<?php $current_url = home_url( $GLOBALS['wp']->request ); ?>
<a href="<?= esc_url( wp_login_url( $current_url )  ); ?>"><?php _e( 'Log in' ) ?></a>

#3 Authorize and go to the home page: 

<a href="<?= wp_login_url( home_url() ) ?>" title="Login">Log in</a>
