FIDO-Based Authentication to Replace SMS-Based Verification, Says UK NCSC

The U.K. government is set to replace SMS-based verification systems for digital services with passkeys this year in a bid to shore up cyber defenses.

The initiative will be rolled out by the U.K. National Cybersecurity Center using the open authentication standard Fast IDentity Online, or FIDO, as a more “secure and cost-effective solution.”
“The NCSC considers passkey adoption as vital for transforming cyber resilience at a national scale,” the NCSC said. “In addition to enhanced security and cost savings, passkeys offer users a faster login experience, saving approximately one minute per login when compared to entering a username, password and SMS code,” the agency said.
The government will introduce passkeys to access digital services starting late this year. Users can log in to the U.K. government’s website to access the passkeys, said NCSC CTO Ollie Whitehouse at the CyberUK conference on Wednesday.
Passkeys can be integrated into phones or laptops and will not require users to rely on additional authentication mechanisms such as SMS-based verification. Users can simply log in into government services to verify their identities.
Passkeys are stored on the users’ phones, so they cannot be intercepted or stolen and are phishing-resistant. “As a result, even if someone attempts to steal a password or intercept a code, they would be unable to gain access without the physical device that contains the passkey,” the NCSC said.
Even if the device is stolen, since the data would be encrypted on the government’s end, risks from compromised devices would be limited, a government official told CyberUK attendees.
“So, the passkey itself is still protected in terms of being able to use the passkey. It’s the same as phones. You still need to be able to log in and unlock the device. So, the only scenario in which a passkey would present an issue is where someone had both the device and they knew the login and they were able to log into the device,” the official said.
