Years ago, one of the most frequently recommended security steps for a WordPress site was to move the login page.
But that’s no longer the case.
If you decide to move the login page, you may actually bring your WordPress site down.
As Chris Wiegman explains in Please Stop Hiding wp-admin, there are many reasons you don’t want to hide the login page.
One reason: you have more ways to log in to WordPress, including the dashboard, REST API, GraphQL, and other authentication options.
Moving one or all can break a site that depends on that functionality.
Web hosts offering managed WordPress hosting can manage security and block attackers.
Ultimately, if you want to improve your site security, use a good web host, update your site, and make sure you’re not using insecure plugins.
