Fingerprints and iris scans are not equivalent to a username or email, since the username and email can be changed easily. Proper biometric data cannot be changed, it is tied to the individual. So when the data is compromised and published in the wild and the devices can be fooled with it (which will always be possible), then the user of biometric recognition devices can become the victim of identity theft for the rest of their life.
