Why do I see sso.knorish.com at the time of sign up or login?

Single sign-on (SSO) is an authentication scheme that allows a user to log in with a single ID and password to any of several related, yet independent, software systems. This allows you to login across Knorish platforms without the need to signing up on the various sites.

In other words, an SSO adds a layer of security to your account.

Additionally, as we build more features into the platform, SSO is the first step towards a social sign-in feature that will be released soon for all creators to use on their online academies for students to sign-in with.
