Is it possible to use ssh-keygen to create an ssh key without a password?

Using ssh-copy-id, you can upload a public key to a remote server and connect without a password. However, you should not enable passwordless authentication for all systems. Instead, use it to access systems you use frequently.

Can you use SSH without password?

Public key authentication can allow you to log into remote systems via SSH without a password. Even though you will not need a password to log into a system, you will need to have access to the key. Be sure to keep your key in a secure location.

What type of key allows a user to access an SSH server without a password?

RSA keys allow users to SSH into a system without having to enter a password. Instead, a locally stored key file is authenticated using the RSA cryptosystem (read more here).

Can I generate a new SSH key?

You can generate a new SSH key on your local machine. After you generate the key, you can add the key to your account on GitHub.com to enable authentication for Git operations over SSH.

Will ssh-keygen overwrite existing keys?

If you already have . ssh/id_rsa key file, running ssh-keygen just like that will indeed overwrite that key (it will ask before overwriting it though). However, id_rsa is just the default name for RSA key type. You can have as many keys as you want with any names you want.

How do I generate SSH key automatically?

Generating a SSH key

From the SSH section, select Create SSH Key. In the Create SSH Key dialog, enter a Key Name and then select Create Key. The private and public SSH key pairs generate.

Can I have a SSH key without an passphrase?

When creating SSH keys, you can create them with or without a passphrase. If you do create a key with passphrase, you will be asked for passphrase every time you try to communicate with your Git repository in Beanstalk. Using passphrases increases the security when you are using SSH keys.

Is SSH passphrase same as password?

A passphrase is similar to a password. However, a password generally refers to something used to authenticate or log into a system. A passphrase generally refers to a secret used to protect an encryption key.

Is passphrase the same as password?

A password is a short character set of mixed digits. A passphrase is a longer string of text that makes up a phrase or sentence.
