SSO authentication means that users use their institutional username and password (not Sketch Engine username and password) to log in to Sketch Engine.
Default storage space
Each new user receives 1 million words for their user corpora. This million cannot be managed by the administrator.
Additional storage space
In addition, the institution may have purchased or been granted additional storage space which the admin can assign to the individual users.
How to manage
Click the rightmost icon in the top right corner of the screen, then Local administration.
The screen shows how much space each user has and how much additional space there is left to be assigned. Use the local menu next to each user to make any changes.
