UK widens passkey rollout to 23 million One Login users, saving nearly £600 a day
↗
The UK government is expanding passkey sign-in across GOV.UK One Login, offering 23 million users a password-free option that already accounts for nearly 10% of daily logins and saves nearly £600 a day in SMS costs.
Passkeys reduce phishing risk by replacing reusable passwords with cryptographic credentials tied to the service, and this rollout signals a major government shift toward passwordless authentication. For engineers, it means building and maintaining systems that support passkey standards while keeping password-based flows intact for users who opt out.

Passkeys are now available to more than 23 million GOV.UK One Login users following a trial with over 300,000 participants.
Nearly one in ten daily One Login sign-ins already use passkeys, which the government claims are up to eight times faster than password plus 2FA.
The switch saves taxpayers nearly £600 a day in SMS costs, and passwords remain optional for users who prefer them.
