Passkeys make login faster. Here is the data, and how to roll them out in Keycloak
Every second a customer spends on your login page is a second they might spend somewhere else. Typing an email and password, mistyping it, waiting for a code, switching to an authenticator app, or giving up and resetting the password are all time between someone deciding to sign in and actually getting in. Passkeys remove most of those steps, and every large published measurement shows the same result: sign-in with a passkey takes about half the time, or less, and fails far less often. Our own customers report the same: after introducing passkeys, they measured login times drop by several seconds per sign-in.
This post collects the published figures, explains where the time goes, and shows how to introduce passkeys in Keycloak alongside the password login you already have.
