Replacing Passwords with Biometrics
The discussion
Liam: Our IT department wants to replace passwords with fingerprint and face login across the whole university. I think it's overdue, because half the help-desk tickets are password resets and people reuse the same weak password everywhere anyway.
Chen: The convenience is real, but you can change a leaked password and you cannot change your face. If the biometric database is ever breached, every student is exposed for life, and universities get hacked constantly.
Ngozi: My objection is more practical. Fingerprint readers fail for people with certain skin conditions, and face recognition is less accurate for darker skin, so some students would be locked out of the library while others walk straight in.
Liam: Modern systems store a mathematical template on the device, not an image, so a breach doesn't hand anyone your actual fingerprint. And the accuracy gap has narrowed a lot in the last few years.
Chen: If the template really stays on the student's own phone rather than a central server, that answers most of my concern. I'd still want passwords kept as a backup rather than deleted.
Ngozi: Narrowed isn't the same as closed, Liam. I'd only accept this if biometrics are optional and a card or password works just as quickly for anyone who prefers it.
