Secure & tested
Rolling your own Two-Factor Authentication is hard and even a simple mistake could be a serious security vulnerability. Authy has been externally tested and validated. We take security very seriously.
Plug & play
Our API takes care of most of the hard details and exposes only 2 simple end-points. Plus we provide libraries for all major languages.
Great user experience
You connect to Authy using a transparent REST API which allows you to customize the experience you want for your users.
Multiple ways to authenticate
We support any cellphone. We provide apps for all major phones (iPhone and Android) as well as text-messages for other cellphones.
Hardware dongles, servers, software licenses, setup costs... It's 2013, forget all that. Authy is bringing two-factor authentication to the present.
The Authy API is deployed accross different PCI level 1 data-centers and it's fully redundant. We also use a DNS provider with anycast support. We've had 100% availability since 2011.
