T-Mobile rolled out phishing-resistant, modern passwordless authentication with device-bound passkeys

SANTA CLARA, Calif. & STOCKHOLM, January 21, 2025--(BUSINESS WIRE)--Yubico (NASDAQ STOCKHOLM: YUBICO), the leading provider of hardware authentication security keys, worked with T-Mobile US to deploy over 200,000 FIDO2 YubiKeys to its teams including employees, vendors and authorized retail partners in late 2023. The passwordless, device-bound passkeys replaced legacy authentication to further secure the Un-carrier’s work systems and information amidst the growing escalation of cyber threats, stopping unauthorized credential use by bad actors over the last year.

Enterprises and other organizations that rely on legacy multi-factor authentication (MFA) methods like passwords and one-time passwords (OTPs) can be susceptible to one of the most common tactics used by bad actors — phishing attacks. Typically, this involves sending a fake or fraudulent email, text or other communication in an attempt to steal someone’s sensitive information.

With Yubico’s FIDO2 security keys, T-Mobile’s teams no longer have to change or remember their passwords, or type in OTP codes that could be intercepted by bad actors; they use their YubiKey to passwordlessly authenticate and verify their identity to gain access to the resources they need.

"T-Mobile took a critical step forward to further reduce credential phishing by deploying the stronger, device-bound passkey solution that Yubico offers," said Jeff Simon, chief security officer, T-Mobile. "Once we had our YubiKeys in hand we were able to get them up and running across the company in less than three months, and we’ve seen the positive results after just one year of having them. That progress is even more important in today’s environment where bad actors continue to wage sophisticated campaigns to attempt to infiltrate telecommunication networks. YubiKeys continue to be an important element of how we approach cyber protection."

"AI and the sophistication of bad actors continue to evolve, putting enterprises and their personnel at higher risk than ever before. To protect against phishing attacks, companies need to act now to adopt and implement hardware-based security keys, which are the strongest multi-factor authentication available," said Jerrod Chong, president and COO, Yubico. "T-Mobile’s deployment of YubiKeys is a great example of how enterprises committed to cybersecurity can rapidly and effectively deploy YubiKeys to reduce phishing."
