ZenKey

ZenKey is a network-based identity management solution that was developed as a collaboration among major U.S. wireless carriers, including Verizon, AT&T, and T-Mobile. Launched in 2020, ZenKey aimed to provide passwordless authentication by utilizing unique carrier network signals to verify user identities. The service offered multi-factor authentication, identity validation, and a dedicated mobile app to streamline user onboarding and authentication. ZenKey targeted businesses looking for efficient authentication workflows and consumers seeking secure login options. Its applications were particularly relevant in industries such as financial services and healthcare, where high-security identity verification is essential. The system relied on carrier-specific data to authenticate users, reducing the need for traditional credentials. As of 2023, the future of ZenKey is uncertain, with reduced involvement from major carriers. Despite this, Verizon still references ZenKey as a free security tool.
