@commandncode: Passwords and SSH keys both authenticate users—but one relies on a shared secret, while the other relies on cryptography. Passwords * Can be guessed or reused * Vulnerable to phishing and brute-force attacks * Require the server to store password hashes SSH Keys * Use a public/private key pair * The private key never leaves your machine * Resistant to brute-force and credential theft * Preferred for servers, cloud infrastructure, and automation #linux #software #computerscience #programming #code
