Allow Multiple Accounts vs Magic Login Mail or QR Code

Allow multiple user accounts to be created, registered, and updated having the same email address. By default, WordPress only allows a specific email address to be used for a single user account. This plugin removes that restriction. The plugin’s settings page (accessed via Users -> Multiple Accounts or via the Settings link next to the plugin on the Manage Plugins page) provides the ability to allow only certain email addresses the ability to have multiple accounts (such as if you only want admins to have that ability; by default all email addresses can be used more than once). You may also specify a limit to the number of accounts an email address can have (by default there is no limit). The settings page also provides a table listing all user accounts that share email addresses (see screenshot). Compatible with Multisite and BuddyPress as well.
