FIDO2 is a standard for
authenticating users without the need for passwords. While the technology has
been introduced mainly to protect accounts on web sites, it’s also useful
for other purposes, such as logging into Linux systems. The same technology
can even be used beyond authentication, for example to sign files or Git
commits. A couple of talks at FOSDEM
2023 in Brussels presented the possibilities for Linux users.
