Single Sign-On (SSO)

Only a single login: fast access to all platforms with Single Sign-On

What is Single Sign-On?

Single Sign-On (SSO) refers to the process of “one-time login” and “Stay logged in”. With the help of SSO, the user gets access to services, applications or resources via a one-time authentication process. Thus, Single Sign-On creates an identity of the user across all systems. In the process, various credentials and different authentication procedures are replaced by a uniform and unique login. This ensures that switching between applications runs smoothly and remains so until Single Sign-Off.


One-time registration, access all digital channels and use all services comfortably.

With Single Sign-On, the user gets a uniform login across to all the channels and does not have to remember different login data, which is quite common at present. With a single login, the user can thus reach all systems of the company. Additionally, digital identities can be managed centrally, which significantly reduces the workload for administrators.

Time saving

Besides the high and time-consuming logins, the numerous credentials also require various password updates from time to time or often lengthy “password forgotten” activities. With Single Sign-On, the user avoids the tedious password processes for many different accounts and, after only one login, gains access to the systems.



With cidaas, the user can choose one of the 12 different authentication methods and thus avoids the passwords which the BSI considers insecure. In case of a password as the authentication method, the Single Sign-On significantly reduces the frequency of input and thus the risk of attack by cyber criminals. Furthermore, a user is more likely to remember a “strong” password and thus tends to choose a simple combination of characters less often.

How exactly does a Single Sign-On work?

If a user needs different applications, which in turn have different accesses, numerous access data are required. The user must therefore remember login data for all applications he wants to access.

With the help of an Identity and Access Management (IAM) system, a created identity can be used for different applications. Each access request is checked against the IAM system to ensure that the user is authenticated and authorized to access the resource. Functionally it looks as follows

The user accesses the desired digital service. The service communicates with the IAM system to check whether a valid token is available. In case of a valid token, the user is taken to the login page. After successful login, the IAM system issues a new valid token to the application Provided that the token is valid, the user is granted access to the resources authorized for him. A smooth Single-Sign-On procedure works with the help of the standards: Open ID ConnectOAuth2 and SAML.

Business to Consumer/ Customer

Inspire customers with smooth access to applications or services. Customers can move through all the digital services provided by a company, such as portals and online shops, without registering.
For example, customers can also register and stay registered directly via popular social login providers:

  • Facebook
  • LinkedIn
  • Twitter

Impress your customers with modern authentication, single sign-on and an excellent user experience on your platform.

Business to Business

To make it as convenient as possible for B2B customers or partners to access their own systems, Single Sign-On is also used here. Thus, in addition to remaining logged in, different identity providers, e.g. those of the customer or partner, can be integrated very easily.

Business to Employee

With the SSO feature, the deployment and management of employees can be simplified. Since an employee has a unique digital identity, authorisations are managed centrally for all systems. This creates transparency and less administrative work. With a single log-in, employees can move between the different systems without the need to log in. Best of all, the onboarding and offboarding of employees is also simplified. Because only one single account needs to be activated/deactivated instead of maintaining numerous individual accounts.
