# SSH Keys

SSH keys saved on your account are the ones you can put on a pod when you rent it, so you can log in with `ssh`. The rent form on lium.io selects your first saved key; pick the others under **SSH Key** if you need them. The CLI and SDK install the key they are given or configured with, and an agent on the hosted MCP installs every saved key unless it is given a specific one. This page is about SSH keys; for keys that let the CLI, SDK or an agent use your account, see [API Keys](./api-keys).

**Add an SSH key to your account**

1. At [lium.io](https://lium.io), open **Access** → **SSH Keys** in the left menu.
2. Click **ADD NEW**.
3. Enter a **Name** and paste your public key into **Key** (for example the contents of `~/.ssh/id_ed25519.pub`).
4. Click **ADD**.

No key yet? Run `ssh-keygen -t ed25519` and paste the `.pub` file it makes.

**With the CLI**

`lium ssh-keys sync` adds every local public key that is not on your account yet. See [`lium ssh-keys`](../developers/cli/reference/ssh-keys).

**A running pod**

A new key reaches new pods only. To add it to a pod that is already running, follow **Add another SSH key to a running pod** in the [Quickstart](./quickstart).
