 ## Notices
 
+* Password-protected ssh keys: since the underlying tool age/rage do not support ssh-agent, password-protected ssh keys do not work well. For example, if you need to rekey 20 secrets you will have to enter your password 20 times.
 * If you want to manage user's hashed passwords, you must use a version of NixOS with [commit e6b8587](https://github.com/NixOS/nixpkgs/commit/e6b8587b25a19528695c5c270e6ff1c209705c31), so the root-owned secrets can be decrypted before the user activation script runs. Currently only available on `unstable`.
