How passkeys work: A technical primer on passkeys

Every year, new data is released that confirms what we already know: passwords are a weak link in the security chain that also ruin user experience. Enter: passkeys, an evolution of FIDO2 authentication that enables faster, easier, and more secure sign-up and sign-in experiences for consumers.

In this technical primer, we aim to:

• Explain how passkeys work from a technical point of view
• Illustrate the standard authentication flows passkeys support
• Touch on implementation considerations for developers
