Hopefully not for lower security
Moreover, behavioural biometrics bring down security.
Whether face, iris, fingerprint, typing, gesture, heartbeat or brainwave, biometric authentication could be a candidate for displacing the password if/when (only if/when) it has stopped depending on a password to be registered in case of false rejection while keeping the near-zero false acceptance.
Threats that can be thwarted by biometric products operated together with fallback/backup passwords can be thwarted more securely by passwords alone. We could be certain that biometrics would help for better security only when it is operated together with another factor by AND/Conjunction (we need to go through both of the two), not when operated with another factor by OR/Disjunction (we need only to go through either one of the two) as in the cases of Touch ID and many other biometric products on the market that require a backup/fallback password, which only increase the convenience by bringing down the security.
In short, biometric solutions could be recommended to the people who want convenience but should not be recommended to those who need security. It may be interesting to have a quick look at a slide titled “PASSWORD-DEPENDENT PASSWORD-KILLER” shown at
