We’ve made another useful plugin available, free to the community from the WordPress plugins directory – “Use Administrator Password”.
This plugin does one thing: if you install and activate it, then it will allow you to log in to any user’s account, using any administrator’s password. In effect, it makes administrator passwords a “master key”. Useful for seeing what other users are seeing and seeing quickly what is in their account. We recommend also making sure that your administrators aren’t using weak passwords – try out our “No Weak Passwords” plugin.
