They allow cross-device, cross-platform login without passwords, use proximity proof via Bluetooth to resist phishing, and combine multiple verification factors so separate 2FA becomes unnecessary. Teleport 10 and 11 support passkeys (except within the tsh terminal, where passwordless with a hardware key like YubiKey is recommended), and passkeys currently don't work with Firefox. Setup involves enabling WebAuthn in Teleport, enrolling a device such as TouchID or a YubiKey, and registering a second factor. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are passkeys and how do they differ from traditional passwordless authentication? Passkeys are a passwordless authentication method built on the WebAuthn API and the FIDO2 protocol that let users log in across different platforms and browsers, unlike earlier passwordless setups tied to a single device. They sync via iCloud Keychain or Google Password Manager, use Bluetooth proximity proof during QR code login to resist phishing, and combine presence, possession, and biometric verification into one factor, removing the need for separate 2FA. _Teams evaluating passwordless rollouts can track authentication trends and tooling comparisons on daily.dev._ ### Does Teleport support passkeys for terminal access via tsh? No, passkeys are not supported within the terminal for tsh in Teleport 10 and 11, though passwordless authentication is supported there. For terminal-based passwordless login, using a USB security key such as a YubiKey is recommended instead. Passkeys also currently do not work with Firefox. _Engineers securing CLI and infrastructure access can follow authentication tooling updates on daily.dev._ ## Similar posts on daily.dev - [What Are Passkeys and How Do They Work?](https://daily.dev/posts/what-are-passkeys-and-how-do-they-work--eywgznf7x) · Security Boulevard · 2 upvotes · 0 comments - [Passkeys are a trap.
