Two-factor authentication will not only gain in popularity but will be the norm within two years, says Chester Wisniewski, senior security advisor at Sophos. RegardingID’s Gina Jordan spoke with Wisniewski about a Forrester Research report that predicts that two-factor authentication will likely be widespread within two years.

Wisniewski feels that widespread may be a bit of a stretch, but says that mainstream may be a more realistic description. “We’ve already seen the likes of Google, Facebook, banking institutions and online gaming facilities adopt two factor authentication as an optional, additional account verification method,” explains Wisniewski.

Crucial to the expanded adoption of two-factor authentication will likely be public awareness and education. “It’s important to explain to people that the benefits are two-fold in addition to two-factor,” says Wisniewski. “Today, we only authenticate online with something we know–a password–but two-factor simplifies passwords because it has something else to back it up that changes each time you use it.”
