What is a key difference between text-based and biometric passwords?

Text-based passwords can be shared because they are typically simple sequences of characters that can be communicated verbally or written down. Users often share their passwords for convenience or access purposes, which can lead to security vulnerabilities.

In contrast, biometric passwords, such as fingerprints or facial recognition, are tied to a person's physical characteristics and cannot be shared in the same way. These biometric traits are unique to individuals and require specific hardware to verify access, making them inherently more secure against unauthorized sharing.

While the concept of uniqueness applies to both types of passwords, not all text-based passwords are unique by nature, as users can choose the same password. The ability to change biometric systems is often more complex and less straightforward than changing a text-based password, as it involves the security infrastructure rather than simply updating a character string.
