How SaaS SSO Authentication Works in SaaS Applications

Management of credentials in the contemporary work environment may become a troublesome task pretty fast. Every typical employee accesses numerous software platforms every day, ranging from chat applications to accounting software. 

When employees need to make and remember various passwords for all these systems, they start using weak passwords, write them down on post-it notes, or simply reuse them across platforms. 

As a solution to this security problem, companies use SaaS sso authentication, which allows users to access multiple cloud-based applications by using just one set of credentials.

Single Sign-On: Basic Concept

The idea of such a login mechanism may be illustrated through understanding how traditional logins work. In general, all applications have their separate databases of usernames and passwords.

The Single Sign-On concept does not require an integration of any login into an application, but rather works in a way opposite to it. Instead of having independent applications verify passwords, it is a central system, acting as the trusted authority of digital passports. 

Once the user passes the verification at this level, he gets a secure digital passport allowing him to access any connected applications without entering their password anymore.

The Authentication Process in Action

There are several processes and technologies behind the scenes:

• Identity Provider (IdP): This is a centralized system (Okta/Google), where users’ identities are stored and verified via passwords, multi-factor authentication codes, or biometrics.
• Service Provider (SP): This is the SaaS application that users want to access (Slack/Salesforce).
• The Digital Token: Upon successful verification by the IdP, the digital token that confirms the identity of the user is sent to the SaaS app, where it is authenticated and access is immediately granted.

Benefits of Centralized Login

Using unified user login systems will bring numerous benefits to an entire organization in terms of security and productivity:

• Unified Identity Management: The IT managers will be able to control access to all the applications in a company from one dashboard. 
• Enhanced Corporate Security: Since the employees need to recall just one powerful master password, there is a negligible risk that they will use the same weak passwords on various sites.
• Decrease in Helpdesk Calls: Forgotten passwords make up an enormous portion of help desk calls made by IT departments. 

Conclusion

Juggling passwords is a waste of time and creates serious problems in terms of security. Utilization of SaaS sso authentication ensures the perfect solution that combines ease-of-use and foolproof security.
