What is keyboard interactive authentication?
Keyboard-interactive (KBI) authentication is a form of authentication for SSH that mimics the process of keyboard interaction, sending authentication information in the SSH server’s request. SSH KBI adapter uses user name and password information for authentication.
What is SSH keyboard interactive password?
Keyboard-interactive (KBI) authentication is the most recently introduced form of authentication for SSH. It involves the server sending prompts to the client, which the client must respond to correctly to be authenticated.
What is keyboard interactive authentication PuTTY?
One of the authentication methods supported by PuTTY is keyboard interactive authentication, which allows the SSH server to ask an arbitrary question and the user to input an arbitrary response.
Can you SSH as root?
SSH (Secure Shell) is often used for logging into remote servers as root. However, the default configuration in OpenSSH prevents root login using passwords. To enable root login, change the value of the PermitRootLogin configuration option in /ssh/sshd_config.
What is SSH connection in PuTTY?
Secure Shell (SSH) is a network protocol used to allow secure access to a UNIX terminal. PuTTY is the recommended application to use for SSH connections from a Windows operating system. PuTTY allows you to access your files and email stored on the engineering servers.
Are SSH keys PKI?
SSH keys use key pairs based on public key infrastructure (PKI) technology, the gold standard for digital identity authentication and encryption, to provide a secure and scalable method of authentication.
Can root user read all files?
The root account has root privileges. This means it can read and write any files on the system, perform operations as any user, change system configuration, install and remove software, and upgrade the operating system and/or firmware. In essence, it can do pretty much anything on the system.

What is the difference between keeper and 1Password?
Additionally, Keeper uses three layers of encryption keys, starting with the strongest 256-bit algorithm, to protect each password and piece of data within a user’s private vault. Like Keeper, 1Password does not see or have access to any of a user’s data and is encrypted end-to-end using 256-bit keys.
Is it safe to disable password/keyboard-interactive logins?
If everyone who needs ssh access to your server can use a public key, then yes, you can safely and arguably should disable password/keyboard-interactive logins. Not the answer you’re looking for?
How many prompts (questions) are presented during keyboard authentication?
During keyboard authentication zero or more prompts (questions) is presented to the user. The user should give the answer to each prompt (question). The number and contents of the questions are virtually not limited, so certain types of automated logins are also possible.
