WDS Single Sign-On

Single Sign-On (SSO) is one of those features every pointy-haired boss in the world wants on their websites. Managing user accounts and passwords across dozens of work-related sites gets very old, very quickly. The longer time went on, the greater the need for an SSO solution at WebDevStudios (WDS) became. I’ll tell you a little about our implementation of Single Sign-On using WordPress and Google accounts, and how it helps both WDS and our clients simultaneously. What is it?
In the simplest terms, Single Sign-On is a way for someone to access multiple websites using one set of username and password credentials.
The WDS-specific implementation uses Google authentication, primarily because we use the Google apps suite for our work tools. But WDS-SSO can easily support any standard OAuth service. Here’s a list of features we built into our SSO solution:
Google Auth support (including Two-Factor Authentication)
Client/Proxy configuration makes setup a one-time task
Enforces all sites involved to use HTTPS
Uses industry standard JavaScript Web Tokens (JWT)
Multisite support
Selective role maps (including Super Admin) for individuals and/or sites
Support for selective (multiple)
