The default WordPress login URL is example.com/wp-login.php but you can change it to example.com/login and also it will be easy to remember and also to use
Implementing this trick is quit too easy you just have to do some changes in .htaccess file.
Just go to the root of your WordPress directory and first Backup the .htaccess file
Now we have to edit .htaccess file
RewriteRule ^login$ http://example.com/wp-login.php [NC,L]
Just edit the example.com to your sites URL
you can also change your Register URL to example.com/register by using the following code in the .htaccess :
RewriteRule ^register$ http://example.com/wp-register.php [NC,L]
Now Just save it. if you encounter any problem please replace the .htaccess file with old one
