Your customers, members and team see the login page often. By default it shows the WordPress logo and links to wordpress.org.
Your logo, linked to your site
Use the same logo as your header, at a readable size. Clicking it should bring people back to your home page.
Your colors
A background that matches your brand and a button in your main color make the page feel part of your site.
A short welcome message
“Welcome back! Log in to follow your orders” tells people they are in the right place.
Keep it simple
No animations or heavy images: the page must load fast and stay readable.
Do not forget security
A nice login page is also a target. Limit login attempts to stop bots.
Brandly does this in a minute. See the demo and how to stop brute force attacks.
