Authy vs OpenSSH

Authy vs OpenSSH: What are the differences?

Authy: The easiest way to add Two-Factor Authentication to any website or app. We make the best rated Two-Factor Authentication smartphone app for consumers, a Rest API for developers and a strong authentication platform for the enterprise; OpenSSH: Free suite of tools that help secure your network connections. It is the premier connectivity tool for remote login with the SSH protocol. It encrypts all traffic to eliminate eavesdropping, connection hijacking, and other attacks. In addition, OpenSSH provides a large suite of secure tunneling capabilities, several authentication methods, and sophisticated configuration options.

Authy and OpenSSH can be primarily classified as "Security" tools.

Some of the features offered by Authy are:

• Very secure- We take security seriously. We use industry standard secure algorithms (HMAC RFC 4426) and 256 bits keys which are always encrypted at rest.
• Fully redundant- 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.
• Great user experience- You connect to Authy using a transparent REST API which allows you to customize the experience you want for your users.

On the other hand, OpenSSH provides the following key features:

• Free SSH protocol suite
• Encryption for network services
• Strong cryptography

According to the StackShare community, Authy has a broader approval, being mentioned in 25 company stacks & 55 developers stacks; compared to OpenSSH, which is listed in 14 company stacks and 14 developer stacks.
