SSH passphrases
Azure DevOps Services | Azure DevOps Server 2022 - Azure DevOps Server 2019
SSH uses private/public key pairs to protect your communication with the server. SSH passphrases protect your private key from being used by someone who doesn't know the passphrase. Without a passphrase, anyone who gains access to your computer has the potential to copy your private key. For example, family members, coworkers, system administrators, and hostile actors could gain access.
A secure passphrase helps keep your private key from being copied and used even if your computer is compromised.
The downside to passphrases is that you need to enter it every time you create a connection using SSH. You can temporarily cache your passphrase using ssh-agent so you don't have to enter it every time you connect.
