**Abstract:** During the last few years, some of the most relevant IT companies have started to develop new authentication solutions which are not vulnerable to attacks like phishing. WebAuthn and FIDO authentication standards were designed to replace or complement the *de facto* and ubiquitous authentication method: username and password. This paper performs an analysis of the current implementations of these standards while testing and comparing these solutions in a high-level analysis, drawing the context of the adoption of these new standards and their integration with the existing systems, from web applications and services to different use cases on desktop and server operating systems.

**Keywords:** WebAuthn; authentication; FIDO
