This extension allows for recovery credentials to be registered with an RP,
which can be used for account recovery in the case of a lost/destroyed main
authenticator. This is done by associating one or more backup authenticators
with the main authenticator, the latter of which is then able to provide
additional credentials for account recovery to the RP without involving the
backup authenticators. The mechanism of setting this up is outside of the scope
of this extension, however a state counter is defined as follows:

Proof of concept on how one can monkey patch any systemd service and filter its journal output.
By default, systemd services connect the executable's STDOUT to the journal. If the executable doesn't provide a way to configure its output, you're left with redirecting the output somewhere else. And since the options for redirecting systemd services' output are very limited, one of the simplest ways to do it is
