SSH, the secure shell, is often used to access remote Linux systems. Because we often use it to connect with computers containing important data, it’s recommended to add another security layer. Here comes the two factor authentication (2FA).
Ssh2 ssh2.exe is a command-line version of the SSH Tectia Client graphical user interface (GUI) utility. Ssh2.exe is a port of the Unix version. TeraTerm Pro Web 3.1.3 - Enhanced Telnet/SSH2 Client TeraTerm Pro Web is the next generation tool for connecting with remote Telnet and SSH hosts. It is built based on the extremely popular open-source TeraTerm product put out by T. Teranishi in 1999 (click here for original site).

What is two-factor authentication
Multi-factor authentication is a method of confirming your identity using at least two different ways of authentication. The most common and easiest to implement example of two-factor authentication uses a combination of passphrase (a complex password, often made of several words) and one-time-passcode generated by a special mobile app.
We will use the Google Authenticator app available for Android (in the Play Store) and iOS (in iTunes) to generate authentication codes.
What you’ll need
- A computer running Ubuntu 16.04 LTS or above
- A phone running Android or iOS
- A configured SSH connection
- You should understand the danger of stolen passwords.
- You don’t need to know what two-factor authentication is and how it works.

Secure Shell's updated version—SSH2—is considered the standard for data security. The Internet Engineering Task Force (IETF) began developing SSH2 in 2001 in response to known vulnerabilities of SSH1. In addition to improved data integrity, SSH2 also added features, included a unique protocol for secure file transfer (SFTP) and the ability to run multiple shell sessions over a single SSH2 connection.
SecureCRT, VanDyke Software's terminal emulation client, supports SSH2 in order to provide a high level of security and the full functionality of the updated Secure Shell protocol.
Improved Security of SSH2
Like the older version of the Secure Shell protocol, SSH2 delivers data security through a number of mechanisms:
- User authentication
- Host authentication
- Data encryption
Ssh 2.0
However, SSH2 delivers a higher level of security by supporting more and more complex encryption ciphers and message authentication code for data integrity.
Benefits of SecureCRT
SecureCRT allows you to do more than just securely connect to remote machines on your network. SecureCRT comes equipped with a number of features that help IT professionals make network administration tasks more efficient.
SecureCRT allows you to save time by:
Streamlining repetitive tasks
SecureCRT includes a number of task automation tools as well as visual displays and cues that allow you to effectively multi-task when working with a number of active connections.
Customizing your terminal emulation environment
SecureCRT lets you customize buttons and keystrokes, change display themes and session color schemes, and move the tab and button bar to help you manage multiple sessions at a glance and put the commands and functions you perform often where they make most sense to you.
Ssh 20
Because SecureCRT is available for most major platforms—Windows®, Mac, and Linux—you can implement a single SSH2 client organization-wide, minimizing the number of applications that require maintenance.
Get Started
SecureCRT gives you more than just the security benefits of SSH2. SecureCRT delivers a robust terminal emulation client that gives IT professionals the tools they need to save time.
