This plugin allows administrators to create additional login details (username and password) for a registered user account. It restricts the additional logins from accessing their linked user’s profile page, as well as accessing the additional logins panel themselves.
The additional logins can be turned off at any time, preventing users from using the credentials to sign in. Descriptions can be given to logins that you create. Additional login usernames are treated like normal WordPress usernames, and cannot match an existing login. Likewise, new logins cannot have the same username as an additional login.
Useful for when wanting to have a few pairs of login details without giving away the main account’s password, as well as multiple team members, or just for convenience.
