Okta introduced new service - Sign in with Okta
Okta unveiled a new service "Sign in with Okta" that allows employees to sign into third party sites and apps just like they sign in their company applications with a single set of credentials. The new API allows developers to add a few lines code and give Okta customers the ability to sign into one another’s websites in a similar way that OAuth allows you to use your Google or Facebook credentials to sign onto consumer sites. When developers add this functionality, the user sees a “Sign in with Okta” button on the website or service they are accessing. They can then use their Okta login to get into these sites under whatever rules the site owner has defined.
Okta alternatives are: OneLogin, Ping Identity, Centrify, Salesforce Identity, LastPass, Symplified
