Re: [webauthn] Which "pubKeyCredParams" to use? (#1757)

@MasterKale, petrdvorak and other contributors: thanks for this discussion which I find very useful, and even though closed now, perhaps useful to add April 2024 update on my experience with algorithm order.

I'm doing webauthn from scratch with a library mentality, and expect most of my customers to be early-adopters or mobile users with standard platform biometrics (touch or faceid). I thought about not supporting ancient windows Hello users, but I also had those chrome warnings when I left out the legacy -257.

I followed Matthew's suggestion and reorganized my algs to put -8 first, to encourage the more current algorithms to bubble up...sure enough latest Chrome used -8, and ignored -7 which was second in my alg list. I did keep last the -257 alg.

I store the public-key algorithm, so over the next year or so I can measure what percentage if any of my customers will create keys with -257. If anyone is interested shout out to me and I'll post the metrics here or somewhere more useful.

Exciting technology: the way forward!
