I could see using this for fraud detection and then kick off a 2FA flow if it couldn't verify.

However, most biometrics aren't the best single line of verification. You still have to add a backup verification of some kind.

Examples, I was working on my car all weekend and my hands have new calluses on them and my finger print is off. I got a new keyboard and my typing pattern is different, etc.
