Allow Multiple Accounts is a WordPress plugin designed to enable the creation of multiple user accounts linked to the same email address. Traditionally, WordPress restricts each email to a single user account, but this plugin effectively removes that limitation. Users can manage settings through a dedicated page where administrators have the option to restrict the feature to specific email addresses or set a cap on the number of accounts per email. Additionally, it provides a clear overview of all user accounts sharing the same email, enhancing user management capabilities.

The plugin is compatible with both Multisite and BuddyPress, making it versatile for various WordPress setups. It offers three template tags for developers, allowing them to count multiple accounts, retrieve users by email, and check for multiple accounts associated with an email. These functions can be safely invoked even if the plugin is deactivated, ensuring seamless integration into any WordPress theme.
