### Password less
Remove your previous secret as described in the next section, incase you already added one.
Open `/etc/fido2luks.conf` and replace `FIDO2LUKS_SALT=Ask` with `FIDO2LUKS_SALT=string:<YOUR_RANDOM_STRING>`
Import the new config into env:
```
set -a

Then add the new secret to each device and update dracut afterwards `dracut -f`
## Removal
Remove `rd.luks.2fa` from `GRUB_CMDLINE_LINUX` in /etc/default/grub
