Q: How do you compare Yubikey to software tokens?

A: Yubikey as a read-only crypto key, is tamper-proof. Software and passive data stored on a PC are always vulnerable to tampering and virus. And the myth that software is free is incorrect, patching and release management, platform dependency, problem diagnosis all cost heavy technical support. Comparatively, Yubikey is the most worry-free no matter how the OS or browser providers upgrade or patch their software or how customers change their PC, Yubikey always work well with them securely and reliably.
