Is...that...safe?

I'm all for the a DIY solution, but considering how much of a pickle I'd be in if all of my 2FA tokens were inaccessible, wouldn't the average person want some kind of case or shielding around the exposed board?

Give me an enclosure like Samsung's metal flash drives[0], and then I'd be sold.

The Github page has this to say: "The token should be durable enough to survive on a key chain for years, even after going through the wash." [0] I'd guess covering it all with hot glue would provide sufficient protection.

Hot snot gets icky with time, rather use a conformal coating; they're available in spray-form as well (e.g. CRC Urethan or Plastik 70). That being said FR4 is a really tough material and it's quite difficult to pry SMD parts off.

Those Samsung flash drives are nice, I have several. ~22MB/s write, and ~130MB/s read.
