A practical solution for universities and other institutions

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

Difference between SSO and IP authentication

  • SSO is able to distinguish individual users, hence all users may have access to all functions, including those that are user-space oriented like building corpora and subcorpora (e.g. using WebBootCat).
  • IP authentication identifies a machine, not a user, therefore user features, such as creating user corpora or saving view preferences, are not available
  • SSO makes it possible to access Sketch Engine from anywhere
  • IP authentication is usually limited to the machines within the university network

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)
