Argh, Nintendo is making it more and more difficult to *not* use passkeys. Which on it's own, fine. But they also don't feature detect correctly and reject any of my browsers on desktop entirely. Plus, I've had any number of sites just not recognize my existing passkeys lately, with (as always) zero actionable error messages.
I was almost in a good space with all this, but passkey implementations continue to be both exceedingly high-maintenance *and* aggressively forced.
