Single sign-on allows users to log on to a computer workstation within a network once with password protection to access software applications, data or services. Data transmission is encrypted.

Pros and cons

Advantages result from the fact that multiple logons are not necessary for different applications. The centralisation of authentication data contributes to data security on the one hand, because passwords do not have to be stored several times. On the other hand, the security risk is also increased because one-time unauthorised access to the data is sufficient to gain access to several applications.

Area of use

Single sign-on is one of the standard authentication procedures for closed shops with a defined user group in companies (intranet) and is used, for example, in web-to-print, web-to-publish solutions and marketing portals.
