How can my mobile device help verify my identity?

A way your mobile device can help verify that you are who you say you are when logging into your online accounts through the use of one-time passwords (OTPs). Online service providers from banks to email providers are starting to use text messaging to send OTPs to help verify your identity when you access an online account, confirm transactions or make changes to your profile (See the tip “How does Facebook use OTPs for security?”). This type of authentication, known as multi-factor or strong authentication, requires you to have your mobile device and OTP with you physically.

While two-factor authentication is a proven security technology, one of the barriers to the use of two-factor authentication with one-time passwords (OTPs) has always been the cost of providing a separate device to securely generate the OTP. All that changed with the ubiquity of mobile phones, which can become the second factor of authentication. For example, a text message to a mobile phone is a very low cost way to throw a high barrier in front of hackers trying to penetrate corporate IT systems.
