How do passkeys work and are they really resistant to phishing?

In his article, Troy Hunt discusses a new login method known as passkeys, which aims to simplify authorization processes online. Passkeys replace traditional passwords that often lead to security issues and management headaches. This method is based on a cryptographic technique that uses key pairs—one key is stored locally while the other is linked to an online service. This means that users can log in without needing to memorize passwords, significantly enhancing their security. Hunt emphasizes the necessity of educating users about new technologies and encourages the adoption of passkeys as a standard that makes online life easier. Although this technology is still in its early development phase, its adoption by major companies suggests that it could be the future of internet security.
