UsersWP Restrict User Signups

Open registration can bring unwanted usernames and accounts using disposable or spam-related email addresses into a site's user base. This add-on lets site owners set restrictions for full or partial username matches and block email domains. It also includes a list of disposable and spam-related domains, giving site owners a starting point for setting email rules.

For sites that need tighter control, you can create a custom list of blocked email domains or allow registrations only from specified domains. Username and email domain restrictions can be enabled or disabled independently. The plugin is designed to work with UsersWP, making it suited to communities, organizations, and other sites that use UsersWP for account registration.

Features

• Block username matches: Restrict specific usernames using full or partial matches, so registrations with names that meet your rules are blocked.
• Remove username spaces: Disable spaces in usernames to enforce a consistent format for accounts created through your registration process.
• Block email domains: Prevent signups from disposable and spam-related email domains using the add-on's included domain list.
• Set custom domain blocks: Add email domains to your own blacklist to block addresses from domains you choose.
• Allow selected domains: Limit registrations to specified email domains, a fit for organizations, companies, and educational institutions.
• Control rules separately: Enable or disable username restrictions and email domain restrictions independently to set the rules your site needs.

Best for

• UsersWP community websites
