Version 2.1.0
This version is compatible with simpleSAMLphp 2.0+
It is usable both as a second-factor (authproc filter) or as an authsource ("webauthn:Passwordless" - FIDO2 Passwordless)
For co-existence of existing username/password users, there is a unified login page offering both Passwordless and a username/password prompt in one authsource ("webauthn:Supercharged").
