WordPress 4.5 added the ability to login using the registered user’s email address in place of the username. When this plugin is active, the ability to login using the email address in place of the username is removed, and the label of the input field is changed to reflect this.

No Login by Email Address

Removes the ability to login using the email address instead of the username.

Allow users to login with either Email Address or Username.
Just install the Plugin, no coding experience required.

Login with Username or Email

This plugin inserts a dozen of ads, including graphics, very prominently into the user interface.
Worse, every user can dismiss every single of these messages (separately) and the plugin makes sure to remember this "setting" for every user as a meta value - polluting your database with senseless garbage.
Lastly, the plugin enures not to include an uninstall action hook, so you need to manually clean up this mess.
Well done.  That's how to promote your business.  NOT.



Beware: Scam

Allow users to login with Email or Username while logging in to Wordpress.
