Re: [webauthn] How long the relying party should maintain the challenge and related information? (#1848)

I think in general we could suggest RP's allow challenges to be used _once_ within N minutes, because a user may walk away mid-ceremony and come back, and should be able to immediately re-attempt without needing to request new options. This has been our practical experience working with WebAuthn, mind you, and I suspect other RP's have done something similar without introducing any security issues into the auth flow.
