SSO – a practical solution for universities and other institutions

With Single sign-on (SSO) you do not need a Sketch Engine user name and password. Simply use your university or institutional login details. Your login details will not be shared with Sketch Engine.

There are two models of university-wide licences with a different way of authentication:

  • Single Sign-On (SSO) – authentication via the institutional user name and password
  • IP authentication – no user name and password are needed, anyone connected to the institutional network can access Sketch Engine


  • is able to distinguish individual users, so users have access to all functions, including their own user-space for building corpora, corpus building tools and creating subcorpora
  • the user can log in anywhere – work, home, internet café etc.

IP authentication

  • Sketch Engine only checks if the computer is connected to the university network but cannot distinguish between users
  • Sketch Engine is in read-only mode, i.e. users can access and search preloaded corpora but cannot build their own and cannot create subcorpora, corpus building is not available
  • users can only use Sketch Engine if the computer is connected to the institutional network, typically inside the institutional building(s) or in their immediate proximity if using the institutional WIFI

Can my institution use SSO?

Your institution has to be a member of one of the following identity federations to use SSO:

If your institution is not a member of either of these federations, please contact us.

Technical definition of SSO

Single sign-on (SSO) is a property of access control of multiple related, but independent software systems. With this property, a user logs in once and gains access to all systems without being prompted to log in again at each of them. (From Wikipedia)
