Biometric Security, in relation to cryptocurrencies, usually takes the form of fingerprint authentication.

With advances in technology, fingerprint scanners are now attached to computers using USB or are built-in, and many smartphones and tablets now include them as a way to easily unlock the devices for us.

Fingerprint scanning, as an authentication method, can be used as part of your overall digital asset portfolio security plan.

For example, you could configure your centralized cryptocurrency exchange (CEX) trading account or personal software wallet to require a fingerprint scan to complete a withdrawal or initiate a trade.
