# Delete an SSH key

Delete a key you have finished with, for example when you replace your keys or retire a computer.
You can delete a key once you have taken it off every resource.

## See what uses a key

1. In TIR, open the account menu at the top right and select **SSH Keys**.
2. Check **In Use**: **Not in Use**, or how many resources use the key.
3. For a key in use, select its name to see each resource that uses it, with its type, project, and
   project owner.

A key counts as in use for each instance, virtual machine, and training cluster that has it.

## Delete the key

1. Take the key off every resource that uses it. For an instance, open its
   **Network & Security** > **SSH**; see
   [Connect to an instance over SSH](/tir/tir-instance/how-to/connect-to-an-instance-over-ssh/).
   For a Slurm Cluster, see [Update a cluster](/tir/tir-slurm-cluster/how-to/update-a-cluster/).
2. On the **SSH Keys** page, open the menu in the key's **Actions** column and select **Delete key**.
3. In the **Delete SSH key** dialog, type the key name in **Key name**, then select **Delete key**.

The key is removed from your list.
