Passkeys.com - your ultimate resource for everything related to passkeys. Whether you're new to the concept or an experienced developer, we've got you covered with in-depth guides, easy-to-follow tutorials, and the latest information on passkey technology.
Passkeys are a secure and user-friendly authentication method that can serve as an alternative to or be used alongside traditional authentication methods, such as usernames and passwords. Passkeys provide a simpler and more secure login experience by leveraging the device's locking mechanism, whether based on biometrics (e.g., Face ID, Touch ID, or fingerprint), PIN code, or another method.
With passkeys, users can sign in without remembering passwords, making the login experience faster and safer, using what the user has (biometrics), instead of what the user knows and needs to memorize (passwords).

Passkeys represent a fundamental improvement in security over traditional password-based authentication. Passkeys leverage advanced cryptographic techniques and modern authentication frameworks, providing several key advantages:
--> Phishing Resistance: Passkeys use public-key cryptography, This means two keys are created: one private and one public. The private key stays on your device and is never shared with anyone, making it resistant to phishing attacks. The public key is shared with the service.
--> No Password Reuse: Since passkeys are unique for each service, there’s no risk of password reuse across different sites, a common issue with traditional passwords that can cause multiple account breaches using the same stolen credentials.
--> No Central Password Storage: Service providers do not store passwords, only public keys, which are useless without the private keys. This means that even if a service provider’s database is breached, attackers cannot obtain user credentials.
--> Local Authentication: Authentication is performed locally on the user's device, significantly reducing the risk of credential interception during transmission.
--> Multi-Factor Authentication (MFA): Passkeys can serve as a form of multi-factor authentication by combining something the user has (the device that stores the private key) with something the user is (biometrics) or something the user knows (a PIN).
Passkeys offer increased convenience for both users and developers. For users, they provide phishing protection, eliminate the need for passwords, and enable smooth multi-device access. Biometric data stays private on the device, and passkeys combine multi-factor authentication into one easy step, instead of entering a code or opening an app.
For developers and online business owners, passkeys bring in stronger, phishing-resistant security and reduce the risk of breaches. They improve user conversion rates with a smoother login process and cut maintenance costs by removing password recovery support and management. Compliance with security standards becomes easier as sensitive credentials no longer need to be stored.
Top tech companies like Google, Apple, Samsung, Amazon and Microsoft are already supporting passkeys, signaling a major shift in online security.
Whether your end users are using Android, iPhone, Windows, or other devices, passkeys are becoming the standard, providing passwordless logins across platforms. With these tech giants backing passkeys, it's clear that this is the future of secure, hassle-free authentication.

Passkey vs Passwords
Passwords have long been the weak link in online security, with studies showing that 81% of data breaches are caused by stolen or weak passwords. Passkeys offer a more simple and secure alternative, leveraging advanced encryption and biometric authentication to eliminate the risk of phishing and password breaches.
Unlike passwords, which can be easily forgotten, reused, or guessed, passkeys remove the need to remember complex combinations. Discover the key differences in security, convenience, and user experience in our detailed Passkey vs Password comparison.
Passkey vs 2FA
Passkeys extend security beyond traditional 2FA inherently acting as a highly secure and streamlined form of authentication.
While most 2FA requires an additional step, like entering a code or opening an app, passkeys integrate several layers of verification into one smooth motion. Using biometrics or a trusted device, passkeys verify your identity instantly, offering the same level of protection as 2FA but without the hassle. With no passwords to remember, and no extra steps, passkeys will enable stronger, faster, and more user-friendly security.
Passkeys simplify and enhance security without compromising on safety.
FIDO Alliance and Webauthn
Passkeys are powered by FIDO (First IDentity Online) Alliance standards, providing secure, passwordless authentication across devices. They are modeled from FIDO® W3C Web Authentication (WebAuthn) and Client to Authenticator Protocol (CTAP) specifications. Learn more about how these technologies enhance security in our FIDO Passkey guide and WebAuthn overview.
