Add Login Text lets you customize the login screen by adding additional text above the login form. Great for developers working on client sites who want to include support links, bylines, mission statements or MOTD.
Use it for:
<ul>
<li>Welcome message</li>
<li>Copyright statements/credits</li>
<li>Link to support forum</li>
<li>Link to your other products</li>
</ul>
Or maybe you are just a regular guy who wants to put something on the login screen. Put a link to your site or whatever you want to see.
For changing the WP logo on the login screen, use a plugin like https://wordpress.org/plugins/login-logo/ instead.
