Missing WordPress login page
If you cannot log in to your WordPress website using the default settings and URLs such as wp-login.php or wp-admin, you may redirect to a 404 error or page not found screen. You may be using an iTheme security pro plugin, which has changed your login URL slug to something else.
A URL slug is an easy-to-remember string that identifies a specific page on your website. In other words, it’s the part of the URL that describes the page’s content in detail. You can proceed if you remember your login URL slug. However, if you don’t, please disable the iThemes ‘Security Hide Login’ feature before beginning your backup or migration process. If the migration is complete, we recommend that you create a new WordPress installation, export the backup, and deactivate the iTheme security pro plugin.
