Water Resistance? (solo2 in a wristband?)

[colemickens]

How water resistant is the Solo2?

I really want to commission a custom wristband that would allow to conceal a Solo2 (and separately my building's access fob) with maybe some sort of magnetic USB connector exposed. I could then tap my wrist to my phone for NFC operations, and/or use it tethered to my computer via the magnetic usb cable (and worst case scenario, I guess potentially destroy the wristband to retrieve the original-form device.

Obviously, water would be a bit of a concern here. I'm not sure how the Solo2 will handle potentially being "soaked" in the wristband if it gets wet, I'd be concerned about the magnetic connector, but I know I've washed my Yubikeys before and they've come out the other side. (Also, not that it's a fair comparison given the size of the efforts behind them but the Yubikeys strike me as a bit more tolerant of abuse than the Solo2 keys.)

Any thoughts? Anyone else stupidly obsessed with the idea of "wearing" their security key? Maybe you have some fun ideas, too?

pretty much all PCBs are fine with getting wet its only when you plug them in and they are wet you have a problem. Salty water (i.e. sweat) may present an issue however if it is "soaked" long term with corrosion, especially the Type-c version as the rest of the contacts on the PCB are ENIG but the type-c connector is off the shelf of unknown material.

Cant testify to the durability of the solokeys as i cant really use mine at the moment but the yubikeys can take a beating - have had a 5c on my keys for close to 4 years and its got no issues.

Whats wrong with putting it on your keys? Presumably you need keys?

To set the right tone, this is some nerdy dorky business, it's nothing terribly serious. I have had a 'yubikey 4+4c' attached to my keyring for years, as well. I can also attest that they take quite a beating, even the longer/thinner full-form usb-a variant.

If I weren't aiming for "the ideal", I'd just solder/glue some sort of magnetic connector to a usb-a yubikey and, with backups in hand, cross my fingers. However, I am still holding out hope that Solo2 will get PIV support soon and I can replace the yubikey(s) with some good ole rust/oss.

There are some times where I'm places that I'd prefer to not have to have my keys or keep track of them. And sadly, despite my attempts at being methodical, I seem to keep losing things. I hope that would be harder to do if said item were strapped to my wrist. My normal keys include my mailbox key, physical-fallback door key, a quickish-style detach ring, etc -- not something I would want to strap to my body.

There is one more possibly even sillier reason to have a wrist attached device...
