Issue with counters? #49

Open stikonas opened 1 year ago

stikonas commented 1 year ago

I've tried it on a few websites (e.g. Gitlab on invent.kde.org, my own Gitea/forgejo instance, github.com) and authentication only works once. I have STLINK token without buttons.

Any ideas how this can be debugged?

Update: hmm, https://demo.yubico.com/playground seems to work more than once.

When checking with https://webauthn.bin.coffee/ it looks like STLINK device always has Counter: 00000100 Flags: 1 no matter how many times I click "Get Assertion" whereas yubikey device has monotonically increasing counter.
