In plain English
It lets one sign-in carry across more than one separate application or service. After that first sign-in, the person is recognized in the others without signing in again to each one.
In context
Here, “SSO” labels a sign-in option that uses one sign-in to authenticate the person across multiple separate applications or services instead of requiring a separate sign-in to each one.
- Situation
- SaaS sign-in, invitations, roles, permissions, and account status
- What it communicates
- labels a company-account sign-in option on the access screen.
Meaning limits
By itself, the term does not say which separate applications or services are covered or whether this sign-in method is available for a particular account.
Examples
“Once Nia had signed in through SSO to the payroll application, she opened the leave and expenses services without signing in again.”
“At sign-in, the contractor chose SSO for the support portal instead of using separate sign-ins for that portal and the training service.”
