--- title: "Passkeys & Passwordless Authentication in ZITADEL" description: "Implement modern phishing-resistant passwordless authentication with FIDO2 passkeys." sidebar_label: Passkeys --- ZITADEL's passkeys feature enables passwordless authentication, offering a **smoother and more secure** login experience for your users. This document explains the essential details for developers. ### What are Passkeys? Imagine signing in without passwords! Passkeys, replacing traditional passwords, leverage **public-key cryptography** similar to FIDO2 and WebAuthn. Users rely on their devices' **biometrics or PINs** for authentication, eliminating password burdens. ### Benefits for Developers * **Enhanced Security:** Phishing-resistant passkeys minimize credential theft risks. * **Streamlined User Experience:** Faster, easier logins free users from managing passwords. * **Platform Agnostic:** Works across devices and platforms supporting passkeys. * **Modern Standard:** Complies with the FIDO2 and WebAuthn standards. ### Features * **Seamless Registration:** Create unique passkeys for users on various devices. Optionally pair them with specific users and choose cross-platform or platform-specific options. * **User Control:** Users manage their passkeys directly through ZITADEL's self-service portal, allowing registration, viewing, and deletion. * **Intuitive Login:** Users initiate passkey login by selecting the passkey option and verifying themselves with the device's biometrics (fingerprint, face ID, etc.). * **Intuitive Login:** Users initiate passkey login by selecting the passkey option and verifying themselves with the device's biometrics (fingerprint, face ID, etc.). * **Robust Fallback:** Traditional password login remains available for users without passkeys. ### Developer Resources * **Documentation:** Passkeys Guide: [https://zitadel.com/docs/guides/integrate/login-ui/passkey](/guides/integrate/login-ui/passkey) * [Create Passkey Registration Link API](/guides/manage/user/reg-create-user) ### Notes * Passkey support is still evolving in browsers and platforms. Check compatibility for your target audience. * ZITADEL actively develops its passkey features. Stay updated with documentation and releases. * Passkeys are bound to your domain, thus we recommend configuring a [Custom Domain](/concepts/features/custom-domain) before setting up passkeys. Don't hesitate to ask if you have further questions about integrating passkeys in your ZITADEL application!
