No. A key to your house can be easily changed. You can not change your biometrics without surgery, and even then, you still often can't really change them.

biometrics make poor passwords.

Biometrics aren't passwords. They are unique identifiers and they make the best, most secure access control identifiers there are.

Because security that people use is >> security people won't use

Right. Unique identifiers == usernames, NOT passwords.

You can't change them, therefor they make poor secrets.
