Summary
GitHub has officially launched its passkeys security feature into general availability, following a two-month beta testing period. Passkeys enable cloud-synced authentication using cryptographic key pairs, allowing users to sign in to websites and apps with their screen-lock PIN, biometrics, or a physical security key. This technology combines the security benefits of passwords and two-factor authentication (2FA) into a single step, simplifying secure access to online services. GitHub’s move aligns with industry efforts, including collaborations between major tech companies like Google, Apple, Microsoft, and the FIDO Alliance, to make passwordless logins a reality across devices, browsers, and operating systems. Passkeys are seen as a significant step in enhancing security in the software supply chain, a vital aspect of the cybersecurity landscape.
I haven’t used passkeys yet, but I would hope that you can have multiple keys per site, not just one. So, after going through some initial pain of setting up each individual device, it should be nice having local-only keys for each of them, which you could revoke at any time.
Password managers are also adding support for passkeys, so you should be able to sync them if you so wish.
