Fast User Switching free WordPress plugin

Fast user switching between users and roles directly from the admin bar or the user list – switch from a list or search for users/roles by id, username, mail etc. Use settings to select roles that are allowed to switch user. By default only administrators can switch user. To return to your own user, just log out. A log out link is available in the black top menu, top right, profile submenu. When you impersonate a user, you will be effectively logged in as that user, and acquire the same rights – very convenient for testing rights for users. Also practical for consultants, bureaus and copy-writers who need to create and edit content for customers.
