For easiest installation [download and install the precompiled deb from releases.](https://github.com/shimunn/fido2luks/releases). However it is possible to build from source via the instructions on the main readme.
|

After installation generate your credentials and add keys to your disk as described in the top-level README
|
||||
then add `initramfs,keyscript=fido2luks` to your `/etc/crypttab`
|

|

Example:
|

```
|

sudo -s
|
||||
|
||||
# Insert FIDO key.
|
||||
fido2luks credential
|

# Tap FIDO key
