Yep. Unfortunately, your appearance is biodata. Just like a fingerprint or iris scan.
Some folks give their biodata away just to make logging into a computer easier.
You can’t change your biodata. And if anyone has it, there is risk of your biodata getting into the wild. Then bad things can happen, and you can’t fix it, like closing down an account or changing your password.
Have you ever heard of kids taking a photo of their parent’s fingerprints and getting into a gun safe? Dad couldn’t just change the password. That gun safe is no good anymore, ever. (A very simple example.)
Think twice before surrendering biodata!
You mean that old fingerprints stored in safe memory can't be erased?
