YubiKey holder · For your backup security key

A backup security key only helps if you can find it.

The spare key usually ends up loose in a drawer or rattling around the bottom of a bag, which is the worst place for the one object that gets you back into your accounts. Machined from solid stainless steel and closed with an O-ring, this case keeps it sealed, protected and exactly where you left it.

A YubiKey 5 NFC measures 18mm by 45mm. The bore is 19mm and the chamber is 2 inches deep, so a full-size key clears it.

Security key holder questions

Will my YubiKey fit? +
A YubiKey 5 NFC measures 18mm by 45mm, which is about 1.8 inches long. The bore is 19mm and the shorter chamber is 2 inches deep, so a full-size key clears it with room left over. The Nano models are far smaller and fit either holder.
Can I use the key while it is inside? +
No, and that is the point. Solid steel blocks NFC and there is no way to plug in through the case. This is built for the spare key you store, not the one you tap a dozen times a day.
Why carry a backup key at all? +
A security key is the one thing that locks you out of everything if it goes missing. A second key only helps if you can find it, which is hard when it is loose in a drawer.
Is it really waterproof? +
Yes, an O-ring seal keeps the inside dry through rain, sweat, pockets, and even the washing machine.
What is it made of? +
Solid stainless steel, machined in the USA. There is no plastic to crack and no hinge to wear out.
What if it is not right for me? +
You are covered by our 100% satisfaction guarantee. If it is not right, we will make it right, no questions asked.
