WordPress User Registration Without Username Requirement - ProfilePress

WordPress User Registration Without Username Requirement

We’ve had a number of requests from our customers asking if it’s possible to create a WordPress registration form where users can register without a username. Technically, this is impossible because WordPress requires all users to have a username.

In this tutorial, I will be showing us a fool-proof way on how to create a user registration form without a username field that just works.

Building the Registration Form

* Open up the edit screen of the ProfilePress registration form you are using by clicking on its title in the WordPress backend.

* Remove the username block or shortcode (if you are using the advanced form builder).

* Go to the form settings and check the Disable Username Requirement checkbox.

With the above steps done, users signing up via the registration form will automatically have a username generated for them from their email address.

For example, say a user registered with [email protected], johndoe automatically becomes his username. And if the username already exists, it becomes “johndoe1”.

Modifying Registration Errors

Note: all code snippet in this post should go into your theme’s functions.php file or a site-specific plugin.

Below are the username generated error messages of a WordPress registration form.

  • Username may not be longer than 60 characters.
  • Sorry, that username already exists!
  • Sorry, that username is not allowed.

The code below replaces “username” in these error messages with “email address”.

add_filter( 'gettext', 'change_registration_username_errors', 10, 3 );
function change_registration_username_errors( $translations, $text, $domain ) {
	if ( $domain == 'default' ) {

		if ( $text == 'Username may not be longer than 60 characters.' ) {
			$translations = 'Email address may not be longer than 60 characters.';
		} elseif ( $text == 'Sorry, that username already exists!' ) {
			$translations = 'Sorry, that email address already exists!';
		} elseif ( $text == 'Sorry, that username is not allowed.' ) {
			$translations = 'Sorry, that email address is not allowed.';

	return $translations;

Modifying Login Errors

We should be done by now, but we still need to modify username generated errors in the WordPress login form to make it fool-proof.

The code below does that excellently well.

add_filter( 'gettext', 'change_login_username_errors', 10, 3 );
function change_login_username_errors( $translations, $text, $domain ) {
	if ( $domain == 'default' ) {

		if ( $text == '<strong>ERROR</strong>: Invalid username.' ) {
			$translations = '<strong>ERROR</strong>: Invalid email.';
		} elseif ( $text == '<strong>ERROR</strong>: The password you entered for the username %s is incorrect.' ) {
			$translations = '<strong>ERROR</strong>: The password you entered for the email address %s is incorrect.';
		} elseif ( $text == '<strong>ERROR</strong>: The username field is empty.' ) {
			$translations = '<strong>ERROR</strong>: The email field is empty.';
		} elseif ( $text == '<strong>ERROR</strong>: Invalid username or incorrect password.' ) {
			$translations = '<strong>ERROR</strong>: Invalid email address or incorrect password.';

	return $translations;


We hope we’ve been able to teach you how to build a WordPress (custom) registration form where users can sign up without asking for their username.
