Passphrases are commonly used for keys belonging to interactive users. Their use is strongly recommended to reduce risk of keys accidentally leaking from, e.g., backups or decommissioned disk drives. In practice, however, most SSH keys are without a passphrase. There is no human to type in...
Passphrases can also be used to restrict access to certain services. For example, it can be used as an alternative to a WPA password (replaced with a WPA passphrase) in yourroutersettings, or you could use aSecure Shell(SSH) passphrase to control access to an encrypted SSH tunnel and t...

A passphrase is a string of words, phrases, or characters used as a security credential to protect access to accounts, systems, or encrypted data. Unlike standardpasswords, which are often short and may include a mix of letters, numbers, and symbols, passphrases are typically longer, aiming ...
SSH runs on theTCP/IPprotocol suite in a client-server architecture. SSH provides encryption and authentication using public key cryptography. The most basic use of SSH is to connect to a remote host for a terminal session. The form of that command, as an example, looks like the following:...
Using a long passphrase instead of a short password to create a digital signature is one of many ways that users can strengthen the security of their data, devices and accounts. The longer a passphrase is, the more likely a user is to incorporate bits of entropy, or factors that make it...
Key-based identification can require a passphrase (password) or can function without a passphrase on the encryption key. To use this authentication type, you have to generate an SSH key pair. The key pair consists of a public and a private key. The public key is kept on the server, ...
-pChange the passphrase of a private key file. -qSilence ssh-keygen. -vVerbose mode. -l"Fingerprint" Print the fingerprint of the specified public key. -B"Bubble babble" Shows a "bubble babble" (Tectia format) fingerprint of a keyfile. ...

will use an agent, which keeps your decrypted key in memory. This means you'll only need to unlock it once, and it will persist until you restart, letting you log into your servers securely without a passphrase prompt. You'll want tomake sure your SSH server is locked down, of course...
