This plugin allows you to quickly swap between user accounts in WordPress at the click of a button. You'll be instantly logged out and logged in as your desired user. This is handy for test environments where you regularly log out and in between different accounts, or for adminstrators of blogs with multiple accounts who need to switch between them.

Features

• Instant switching and redirection to the WordPress Dashboard.
• Instant switching back to the originating account.
• It's completely secure (see the "Security" section below).
• WordPress and WordPress MU compatible (watch out for a bbPress version soon).

Security

• Only administrators can switch to another user. Lower level users cannot switch between accounts.
• User switching is protected with the WordPress nonce security system, meaning only those who are allowed to switch users can switch.
• Full support for administration over SSL (if applicable).
• Passwords are not (and cannot be) revealed.
