+- On Firefox on Linux, Nano S Plus is missing in snap udev rules.
+- There are some instabilities on Safari on MacOS, it's recommended to use another browser.
+- Android support on FIDO2 for external security key is not available yet. It should be starting with Google Play services v23.35

 * Following FIDO2 spec, there should be a way to revoked credentials. A revocation mechanism has been implemented based on a counter that - as discoverable credentials - will be wiped upon app deletion. therefore, in order to avoid weird issue on user side, this counter as been disabled. See HAVE_NO_RESET_GENERATION_INCREMENT section on the Makefile for more explanations.
