DNA Passwords!

[Pase]

2013 saw Stanford University reveal DNA being synthetically coded and used as a memory device to store data ( a robust means it would seem).

What are peoples thoughts on the possibility ( some time in the future) of using an individuals unique DNA signature as their access to accounts, with an interface perhaps able to read and verify the persons biometrics/characteristics against their genome? I'm not talking about some means whereby a dude with a flake of someones dandruff could hack their account, but something much more complex.

And perhaps family genetic lines could be determined to ensure passing down of any asset ( where amicable of course!)

Just a thought.
