Every time work pushes to use 100% biometrics I have to argue and get an exception.

I've got form of eczema where two to four times a year all the skin on my hands flakes and falls off... There are weeks when I have no fingerprints.

They've only brought up facial recognition once and I said it didn't work reliably due to my skin color and facial hair. I have no idea if that's true, never tried it, never will, but they didn't pursue it any further.

I always enjoy throwing out the "if you force that, there will be about two months a year where I won't be able to login... That's up to you, but you have to document it so I can forward it to my manager and make them aware". Unfortunately they haven't forced it yet.
