# Access Runtime Overview

> Enable secure SSH access to Runtimes

Use SSH when you need interactive shell access to a runtime.

SSH sessions land as the unprivileged `agent` user. `sudo` is preconfigured with `NOPASSWD`, so administrative commands (`sudo apt-get install ...`, `sudo systemctl ...`) work without a password prompt.

## SSH Lifecycle

1. Enable SSH on a running runtime.
2. Connect with the returned command and private key.
3. Disable SSH when done.
4. Rotate credentials with regenerate\_keys when needed.
