The login page is where you go to access the publishing side of your website. Think of it like the back door into your blog where you can create new posts, add pages, and configure your blog.
All you need to do is add /login/ or /admin/ to the end of your blog's URL.
Once logged in, you’ll be taken directly to the admin area dashboard of your site. Alternatively, you can add /wp-admin/ or /wp-login.php to the end of your site’s URL, which will also take you to the admin area of your site.
Remembering Your WordPress Login URL
You don’t have to remember your login URL off by heart – just bookmark your login page in your browser. You’ll then have a quick way to login to your blog whenever you feel the urge to write a new post.
