Discover how Relai, the Swiss-based Bitcoin wallet app, replaced traditional logins and account recovery flows with Keyless biometric multi-factor authentication.

With over $1 billion in trading volume and 500,000+ downloads, Relai needed a secure yet seamless way to protect user accounts from phishing, PIN theft, and device-level fraud – without compromising on privacy.

By deploying Keyless, Relai now verifies identity using just a face and a trusted device, instantly and privately, with no passwords or seed phrase required.

The Keyless SDK was integrated directly into the Relai app, enabling secure logins, step-up actions, and account recovery with a simple look at the camera.

This partnership demonstrates how biometric authentication can balance security, privacy, and usability in even the most sensitive environments, setting a new standard for trust in crypto.
