You could use a gut biome sample for a password. It changes slowly over time, so you’ve got rolling built in. And you can do a reset with antibiotics.

  Because it’s funny imagining taking a stool sample to log into Snapchat.

I like that if you eat a healthier and more varied diet you end up with a more complex password.

Is this sarcasm? I have accounts I haven't logged into for years, but still need access to. Losing access over time is not a good feature. And a 'reset' with antibiotics doesn't make sense for a bunch of reasons. Also, password diversity is a good thing. I don't want $COMPANY_A's data breach to expose my password to $COMPANY_B

Gut biome actually changes pretty rapidly. IIRC some grad student did some kind of sequencing on his stool for a year, the the populations of different strains of bacteria would completely flip when he ate a salad one day and a cheeseburger the next. His name was Lawrence David, but I can't quickly find the writeup that illustrates the point I'm making.

It's going to be difficult to keep the sensor completely clean for the next person to use.

I already use it as my signature.

Or, we can develop solutions based on existing [proven] cryptographic primitives, with a focus of abstracting authentication / signing / encipherment functionality to an external key or secure-device. Example: iPhone (and Andorid) both have "secure enclaves" where cryptographic keys are stored. However when you step into the basic PC/Linux realm the concept of a secure-device for key storage (TPM) is pretty non-existent outside of corporate players. We can do better, without totally going pie in the sky.

And you can share your password with the rest of your family with a fecal microbiota transplant.
