With Dataswift One's single sign-on service, PDA users only have to enter one set of credentials to access web applications – via desktops, smartphones and tablets. This greatly increases efficiency for the user while keeping their data secure. More importantly, users do not need to even include their identity. They can sign on with data within their PDA, such as their interests, body dimensions and even with computed data such as their mood, in order for your website to personalize its content and service for them.
