Crypto users might soon log in to their favorite platforms using nothing but an old smartphone. Infinex, a growing name in Web3 infrastructure, is beta testing a new Chrome browser extension that allows users to authenticate logins using fingerprint or facial recognition—without needing a new device.

The extension currently supports login access to the top 100 crypto websites, simplifying user access through biometric authentication. Instead of entering a password or using a wallet plugin, users just scan their fingerprint or face on a registered phone—even an older one—and they’re in.
This approach not only improves convenience but could also expand access to secure logins for users in developing regions who still rely on older smartphones.

Infinex’s tool works by linking your browser to your old device through a secure, encrypted connection. Once paired, your phone becomes the key to unlock sites like Coinbase, Binance, and DeFi dashboards.
The idea is to eliminate clunky logins or reliance on hardware wallets. Instead, your device acts as the gatekeeper, using familiar phone-based biometrics you already trust.
However, the exact technical specs, including how data is stored and encrypted, haven’t been fully disclosed yet. Infinex promises user privacy and end-to-end security but has yet to publish a full audit or open-source the code behind this extension.

 INSIGHT: Infinex is beta testing a new Chrome browser extension that enables users to log in to the top 100 crypto sites using any old phone with fingerprint or face unlock. But is it safe? <a href="https://t.co/ra1Qv0v9EX" rel="noopener noreferrer nofollow">pic.twitter.com/ra1Qv0v9EX</a>— Cointelegraph (@Cointelegraph) <a href="https://twitter.com/Cointelegraph/status/1975765793691328831?ref_src=twsrc%5Etfw" target="_blank" rel="noopener noreferrer nofollow">October 8, 2025</a>

While biometric login is common in mobile banking and password managers, using it for crypto logins via a browser extension raises a few flags.
Cybersecurity experts often warn that biometric data, once compromised, can’t be changed like passwords. If Infinex’s system is ever breached, the consequences could be serious. Furthermore, older phones may not have the latest security patches, potentially exposing vulnerabilities in the device used for authentication.
Until a third-party audit is completed, cautious users might want to wait before using the tool for high-value accounts. Still, it’s an exciting step toward simplifying secure access in the crypto space.
