This add-on allows users to be automatically signed into a site, matching either an IP address, have when they have come from a particular URL (a 'referrer URL') or if they have landed on a particular page of your site.
When installed, a new dashboard menu item is installed under the 'Members' section, called 'Automatic Sign Ins'. This new section allows an administrator to:
The add-on doesn't prevent administrators or other users from still signing in to a site with their own credentials as the login screen is still able to be accessed.
Please take care when configuring automatic sign ins, as to not accidentally allow access to editing controls or protected content you aren't intending. The add-on will highlight if when the super administrator user or users in the Administrators group is used, but will not stop you from doing so.
Also note that using referrer URLs to protect content is not completely secure - if the referrer URL is recognised as the reason for access, a technically skilled user can perform 'referer spoofing', to pretend they have come from that URL. Therefore it is recommended to not use this add-on to protected highly valuable resources or downloads.
