Two-factor authentication is the security term on everyone's lips these days, with major global players all moving to this more secure method of self-identification, ranging from manufacturers to retailers and Government agencies alike.

In the latest news, Google has published its offline-enabled authentication app, suitable for smartwatches. Available to download for free off Google Play, this app is thankfully available without being always-online, allowing users to identify themselves efficiently and easily through a wrist-worn device.
There is also word on NFC authentication with this update, meaning that we could see authentication tags and wristbands in the future, meaning users are able to simply tap a product to their phone, computer, tablet or even television to confirm it is actually them.
