How to customise the Wordpress admin login URL

Step 1: Log in to your WordPress site.
Step 2: Click Plugins, and then click Add New.
Step 3: In the Search text box, type rename wp-login, and then click Search Plugins.
Step 4: The Rename wp-login.php plugin appears in the list of search results.
Step 5: Under Rename wp-login.php, click Install Now, and then click OK to start the installation.
Step 6: After the plugin installation finishes, click Activate Plugin. The Permalink Settings page appears.
Step 7: Under Common Settings, select a permalink structure for your site.
Step 8: Under Login, in the Rename wp-login.php text box, type a URL for the login page, or accept the default value of login.
Step 9: Click Save Changes. The new WordPress login URL appears near the top of the Permalink Settings page.
Step 10: Test your WordPress site to make sure that it still functions correctly, and that you can access the login page using the new URL. Additionally, if you try to access wp-login.php or wp-admin, you should receive a “404 Not Found” error message.
