 ## Encryption
-Add a ro mount to your `~/.gnupg` directory and then provide the `GPG_KEY_ID` as an environment variable. The key will be used to sign and encrypt your files before sending to the backup destination.
+By default Duplicity will use a symettric encryption using just your passphrase. If you wish to use a GPG key, you can add a ro mount to your `~/.gnupg` directory and then provide the `GPG_KEY_ID` as an environment variable. The key will be used to sign and encrypt your files before sending to the backup destination.
 
 Need to generate a key? Install `gnupg` and run `gnupg --gen-key`
