We are awash in passwords, and as the number of Web services increases, things are only going to get worse. Trying to manage all these individual passwords is a major problem for enterprise security. Many end users cope by re-using their passwords, which exposes all sorts of security holes.
One solution is a SSO (single sign-on) tool to automate the logins of enterprise applications and also beef up password complexity, without taxing end users to try to remember dozens of different logins.
SSO isn't new: we have had various products for more than a decade. What is new is that several products now combine both cloud-based SaaS logins with local desktop Windows logins, and add improved two-factor authentication and smoother federated identity integration.
Also helping is a wider adoption of the open standard Security Assertion Markup Language (SAML), which allows for automated sign-ons via exchanging XML information between websites.
