+## File based keychains
+
+On linux you can opt to use a file based keyring, instead of a GUI based keyring manager. This is helpful for headless setups such as servers. For this option to work linux users must set an environmental option.
+
+```R
+options(keyring_backend="file")
+```
+
+You will be asked to provide a password to encrypt the keyring with. Upon the start of each session you will be asked to provide this password, unlocking all `ecmwfr` credentials for this session. Should you ever forget the password just delete the file at: 
+`~/.config/r-keyring/ecmwfr.keyring` and re-enter all your credentials.
