OneOffice Auth adds a second layer of security for your online accounts. This works by generating one-time passwords on your mobile devices which can be used in conjunction with your normal password to make your login nearly impossible to hack. These passwords can be generated even when your phone is in airplane mode.OneOffice Auth is a single App that works with many of the great online services you already use, including OneOffice, Google, Facebook, Evernote, GitHub and many more! OneOffice also may work for your private corporate security if you implemented the standardized TOTP or HOTP protocols.
