What single sign-on is
Single sign-on, often shortened to SSO, lets a person use one set of credentials across multiple applications. Instead of holding a separate username and password for each system, the person authenticates once with a central identity, and that identity is trusted by every connected application.
The benefits are practical. Users have fewer passwords to remember and reuse, which reduces friction and improves security. For the organisation, access can be managed centrally: when someone joins, their access is granted in one place; when they leave or change role, it is removed in one place across every connected application, rather than chased system by system.
Single sign-on relies on a trusted identity provider that the applications recognise, so the assurance of the central login carries across all of them.
Single sign-on in the Cohiva platform
The Cohiva suite shares one identity and one control plane across its products. A person signs in once, and that same identity grants access to the products they are entitled to use, such as Complex for operations and Crunch for finance. Because access is managed centrally, it is granted and removed once across the suite rather than configured separately in each product.
