Frequently Asked Questions

What is SSO and How Does it Work?

SSO security refers to single sign-on authentication, a method of logging in to multiple applications in one step. Here’s how it works: When a user logs into a system with their username and password, the integrated SSO software generates a digital token. This token is then used to access connected applications, eliminating the need for multiple logins in a session.

Is SSO Authentication Secure?

To secure the SSO login process, adding an extra layer or two of authentication is crucial. Two-factor authentication (2FA), also referred to as multi-factor authentication (MFA), requires at least one identity verification factor in addition to the password. A passcode sent to an email, facial recognition, or answering security questions are factors that can verify a user’s identity. By implementing SSO with 2FA, you not only streamline access but also significantly reduce the risks associated with compromised credentials. It’s a security win-win.

What is an SSO Token?

An SSO token is a virtual key that represents a user’s authentication. It contains information about the user’s identity and permissions, allowing them to access various applications in a session without the need for reauthenticating at every login. Combined with an effective two-factor authentication (2FA) solution, this token simplifies access and streamlines the user experience without compromising security.

How do I Choose an SSO Solution?

When selecting the best SSO solution for your business, look for one that is:

User friendly: It should be easy to deploy and manage so users can swiftly adapt without sacrificing security.
Integrated with 2FA: Choose an SSO solution that is part of an identity and access management (IAM) platform. SSO and 2FA are a dynamic duo that authenticate users while securing access to the applications they need.
Enterprise-ready: Prioritize robust solutions that cater to all types of users, including partners and contractors. A mature SSO solution supports diverse regions, applications, application types (on-premises, web, and client-based), and common protocols.
Reliable and scalable: For a growing enterprise, select a solution that offers high availability, strong SLAs, and scalability to support your organization’s evolving needs and expanding user base.
Dynamic: Assess a solution’s long-term viability. Does it align with your security goals? Can it adapt with evolving threats? A dynamic solution improves capabilities and support during deployment and beyond.
