Biometrics are ease of access, not security.  They make it easy for you (and low skilled strong arm attackers, skilled hackers, nation state actors, and neo-Nazi police state border and police thugs) to unlock your phone.  As long as you’re good with making it easy for them to unlock your phone by all means, use biometrics.

Using biometrics to provide access to personal data is asinine.

Using biometrics to provide access to any amount of sensitive data is criminally negligent.

Biometrics cannot be changed.  Once you’ve given your palm biometrics, or facial biometrics, or fingerprints, or iris or retinal scans, or facial biometrics to any company or government they are no longer useful.

Just as the 5.6 million people whose fingerprints were lost in the OPM hack in 2015.

But whatever…you do you.  If you want to make it easy for people to access your device, go ahead and use biometrics.
