What is SSO (Single Sign-On)?
SSO allows users to authenticate once and gain access to multiple applications without re-entering credentials. It uses identity protocols like SAML or OAuth to securely pass authentication tokens between services, reducing password fatigue and improving security.
Why SSO matters for Australian businesses
With cyberattacks on Australian businesses increasing year on year, understanding your security tools and strategies is critical. The Australian Cyber Security Centre reports an attack every six minutes, and small and medium businesses are increasingly targeted. Having the right defences in place is not optional — it is essential for protecting your data, your clients, and your reputation.
For small and medium businesses in particular, sso plays a key role in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding sso will help you have more informed conversations with your IT provider and make better decisions for your business.

Frequently Asked Questions
What is single sign-on (SSO)?
Single sign-on lets users access multiple applications with one set of login credentials, so they sign in once rather than separately to each system.
Does SSO improve security?
Yes, when paired with multi-factor authentication. It reduces password fatigue and reuse, centralises access control, and makes it easier to revoke access quickly when someone leaves.
What is the difference between SSO and a password manager?
A password manager stores separate passwords for each site; SSO uses a single trusted identity to grant access to many apps. They solve related problems in different ways and can be used together.
