/ess-ess-aitch kee/

Also known as: public key authentication, authorized_keys

Last updated August 8, 2026

Definition

An SSH key pair authenticates remote logins without (or in addition to) passwords: the private key stays secret while the public key is placed on servers you access.

Real-World Example

Adding your public key to a server’s authorized_keys file lets you deploy with ssh without typing a password each time.
