In a world where we may have dozens of different passwords, it gets tedious to enter credentials all day. Worse yet, because we have so many different passwords to enter, we usually reuse the same ones and make them as easy to type in as possible.
Enter AuthAnvil Single Sign On. Type in your PIN and unique AuthAnvil one-time password that is generated for you (that's right... you don't have to remember it) and gain access to all your systems and services that support federated single sign on. Everything from Salesforce.com to Google Apps to Office 365. There are a wide variety of applications available, but it all starts with AuthAnvil Single Sign On.
