Single Sign-On explained
SSO centralizes authentication. Instead of every application maintaining its own username and password, users sign in once to a trusted identity provider — such as Microsoft Entra ID — and that provider vouches for them to each connected app. One secure login unlocks the whole suite of approved tools.
This both reduces password fatigue and tightens security. With fewer passwords to remember, users stop reusing weak ones across sites. And because access flows through a single identity provider, an administrator can enforce strong policies — like MFA and conditional access — in one place, and instantly cut off access to every app when an employee leaves.
Why SSO matters for your business
Every separate password is a separate liability: another credential to be phished, reused, or forgotten, and another account to remember to disable when someone departs. The more apps a business adopts, the worse this sprawl becomes — and the easier it is for a stale or orphaned account to become an attacker's way in.
SSO collapses that sprawl into one well-protected identity. It improves the day-to-day experience for staff while giving IT central control over who can access what — a foundation for both productivity and a zero-trust security posture.
Scalogic implements SSO around your identity
Scalogic configures Single Sign-On built on Microsoft Entra ID and your existing Microsoft 365 environment, as a Microsoft partner. We connect your business apps to one secure identity, layer MFA and conditional access on top, and streamline how staff join, move, and leave.
The outcome is simpler logins for your team and centralized, auditable control for you — including the ability to revoke access everywhere at once when an account needs to be shut down.
Frequently asked questions
Does SSO reduce security by having one password?
No — done right, it increases security. That single login is protected by MFA and conditional access, and centralizing identity lets IT enforce strong policies and revoke access everywhere instantly.
What identity provider does SSO use?
Many businesses use Microsoft Entra ID, which integrates with Microsoft 365. Scalogic builds SSO around the platform that fits your environment.
Is SSO the same as a password manager?
No. A password manager stores many separate passwords. SSO removes the need for separate passwords by authenticating you once through a trusted identity provider.
