Single Sign-On

Single sign-on lets people access several systems with one set of credentials, authenticated centrally. It reduces password sprawl and makes access something you can grant and revoke in one place.

The Operational Argument Is The Strongest One.

When someone leaves, access has to be removed everywhere, and access removed from nine systems individually is access that will still be live somewhere. Central identity turns that into a single action.

Software engineers collaborating on single sign-on architecture, component code, and system standards — Engineering scalable Single Sign-On minimises technical debt and accelerates deployment velocity.

It also improves security in a less obvious way: fewer passwords means less reuse
central authentication makes multi-factor enforcement a policy rather than a per-system project
The trade is concentration.: One identity provider becomes both a single point of failure and a high-value target, so it needs stronger protection than any individual system it fronts. That is usually a good trade, and it should be made deliberately rather than by default.

Frequently Asked Questions

Is Single Sign-On More Secure?

Generally yes, because it reduces password reuse and makes multi-factor authentication and offboarding enforceable centrally. It concentrates risk in the identity provider, which then needs stronger protection than the systems it fronts.

What Happens If The Identity Provider Is Down?

Access to everything behind it is affected, which is why break-glass accounts and a documented recovery path are part of implementing it rather than an afterthought.

What Does This Cover?
