Log in via your institution

A practical solution for universities and other institutions

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

Difference between SSO and IP authentication

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

How to log in with SSO?

Technical information

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)

SAML 2.0 attributes required by Sketch Engine

To assign a SSO authenticated request to an organisation licence and a user profile in Sketch Engine, the following SAML 2.0 attributes should be released by the identity provider:

  • eduPersonScopedAffiliation (urn:oid: or eduPersonPrincipalName (urn:oid: – mandatory,
  • eduPersonTargetedID (urn:oid: or eduPersonPersistentID (urn:oid: or eduPersonPrincipalName (urn:oid: – mandatory,
  • email (urn:oid:0.9.2342.19200300.100.1.3) – optional (enables responding to user’s support requests, the user will be asked to supply this information if not released by the identity provider),
  • displayName (urn:oid:2.16.840.1.113730.3.1.241) – optional (enables person identification within the organisation, the user will be asked to supply this information if not released by the identity provider).

To find if your institution meets the requirements, SAML2 attributes released by an identity provider can be checked in the Attribute Viewer.

An institution can be checked in the eduGAIN Entities Database for membership and SAML 2.0 support.
