# Hardening Limnoria * Upstream documentation: https://docs.limnoria.net/use/security.html ## Passwordless users *This is subject to moving to the upstream documentation, see [Limnoria/Limnoria-doc#91](https://github.com/Limnoria/Limnoria-doc/issues/91)* Passwordless user accounts have been supported since version 2021-05-27. They must login by some other mechanism such as NickAuth, GPG or hostmasks. Registering a passwordless user happens by `/msg Limnoria user register !`, and existing user may remove their password by `/msg Limnoria user set password !` It's also possible (while not recommended) to edit `users.conf` by hand. 1. `/msg bot flush` to save all current configuration changes to disc 1. `/msg bot config flush false` to disable automatic config file writing 1. Open `botdir/conf/users.conf` with your favourite text editor and remove the lines beginning with `password` 1. `/msg bot config reload` and all the accounts should be passwordless. You may also check that `config flush` is `True`, but the `False` shouldn't have gotten stored to disc anyway as it wasn't written to disc.
