Managed to burn several layers of skin off both of my thumbs recently (through thick gloves while holding a very hot steam hose). It's been three weeks now that biometric (thumb) authentication for all my devices stopped recognizing my hamburger thumbs, which are so covered in crusty new and old layers of skin that texting feels like I've got cleats on my thumbs. Fun times.
@briankrebs I recently did some work on my A/C and despite my thick rubber gloves, I got bit by the refrigerant spilling out. Probably nowhere near as bad as you got, but very fun indeed.
@briankrebs
Ouch.
Tho, that must haven been a calming phone situation, the past three weeks.
@briankrebs Time to start commiting perfect crimes that leave no fingerprints!
@briankrebs Ouch! Hope that your thumbs heal soon. There are simpler ways to defeat fingerprinting. In high school chemistry class, we studied that as a property of NaOH -- rub the top of your fingers with sodium hydroxide and they become really smooth. Washing a sink with CLR without gloves will do that too.
@huitema @briankrebs throwing pottery does it too, the clay being turned against your fingers sands them nicely smooth.
@briankrebs Time for pinky auth. Security through obscurity.
@briankrebs I do woodworking as a hobby and have to add new prints every few months πŸ˜†
@briankrebs living without viable biometrics was super challenging in the final months of my mom's life, as her fingerprints stopped working. being ill isn't a great time to fall back to passwords/PINs either.
@briankrebs
I've just never gotten fingerprint readers to work, period. Not even once. Tried on a series of 4 or 5 devices with different generations & types of fingerprint readers - couldn't get a single one of them to work. I don't even bother anymore.
@FeralRobots @briankrebs My husband was the same (lifetime hands-on mech engineer). Touch screens didn't like him either.
@briankrebs soured on biometrics years ago because I cut my thumb and ended up having to use normal auth for weeks while it healed. With the next phone, I made sure add both thumbs and pointer fingers "just in case".
@ezrasf @briankrebs business continuity planning dictates that everything needs a backup. And that the backup plan account for correlative damage. Good call to use the other hand, for example.
@ezrasf @briankrebs I always make sure to add my middle finger, on general principles
@briankrebs Ouch! now you are also an expert on gloves security.

@briankrebs
That sounds like the most unpleasant credential revocation method. 0/10, do not recommend.

When rock climbing regularly I taught my phone the inside of my pinkie fingerprint, so I could still get in.

@briankrebs Fingerprint != hamburgerprint

@briankrebs My hobby is glassblowing.

Every glassblower has got a few burn stories that make good party entertainment.

Between that and the occasional cut from the shattered glass everywhere, never mind un-annealed glass popping off hot shards at you, suddenly biometric ID seems a little wobblier. πŸ™‚

@briankrebs OK, is this where you write a post with a headline that has "wake up call for..." in it?

J/K... wishing you a speedy and full recovery.

@briankrebs I have very flat ridges on my fingertips, plus sometimes eczema. Fingerprint scanners basically don't work for me.

It was a big problem when I was getting citizenship and they wanted to take my fingerprints.

@briankrebs
Oh god, that sounds painful. Hope you're well soon.
