You can log into web services and cloud apps with two-factor authentication just by being in the proximity of your computer with SAASPASS if your company or service provider has integrated it.

All you have to do is install the Proximity Login Agent and have a computer that supports proximity and a mobile device that supports it as well (the iPhone 4S onwards for example and most Android devices with the OS 5 onwards). For single sign-on capabilities download the SAASPASS Computer Connector or SAASPASS Single Sign-On client and they both support logging in with proximity as well.
