# Auth & CPU servers

## Create user on the file system

## Keyfs user database  


- [https://plan9.io/magic/man2html/4/keyfs](https://plan9.io/magic/man2html/4/keyfs)

<tt>This creates `/adm/keys` encypted (DES?) user database file and mounts its content under `/mnt/keys`.  
</tt>

```
auth/keyfs -p # (in rc terminal, no acme)
```

Now we can crate user in the encrypted `/adm/keys` file:

```bash
auth/changeuser hxd
```

This will write new `/adm/keys` file and also show the user in `/mnt/keys` as parsed out of the file.
