From the last few decades, single sign-on(SSO) solution is benefiting enterprises and users. Businesses are well aware of the benefits of SSO to them. The fundamental principle behind the solution is based on Security Assertion Markup Language(SAML), an XML-based open data package, that authenticates users between a service provider and an identity provider. This SAML based SSO works great with the desktop computer for authenticating websites, but for mobile technologies, it is not enough. Mobile technologies add new layers of complexity that is not possible for first generation SSO to overcome.
In this article, I am going to mention some of the options to improve mobile SSO.
The OAuth 2.0 makes it easy to switch between different applications on the mobile device. The process is accomplished through an authentication server that issues tokens from a known resource. The token is being used to provide safe and secure access to protected resources on HTTP servers. The method works great for public domain and cloud services. Some of the big companies including Google, Microsoft, Facebook and Twitter are using OAuth 2.0. The only limitation of the solution is, at a time only one application can effectively use the solution.
OpenID is a technology that eliminates the restriction of a single application as for OAuth 2.0. The technology allows a single set of credentials to access all the resources of a business. For example, the user can access all the Google service single Google ID and password.
NAPPS and OpenID connect
OpenID and OAuth 2.0 help in providing seamless authentication but they don’t provide profile information for that account. For this, OpenID connect is a good option. It is an additional tool that helps in compiling profile information into JSON packet. Adding NAPPS (native application profile) makes it easier to offer true SSO to mobile and other devices.
Nowadays increase in the number of mobile applications and cloud services increase complexity in our digital life. This result in an increase in complexity while authenticating. Implementing the mentioned technologies definitely makes it easy for customers and users for authenticating mobile devices. No doubt, they are extremely secure solutions.
