Yes, peteyt is spot on. This is exactly what I am checking on to see if ESET Password Manager supports, or plans on supporting in the future, storing and using OPT/2FA/Biometric tokens (in an encrypted fashion). References provided below for two other vendors which I use. From what I can tell in my testing today ESET Password Manager does not seem to provide this feature. If so perhaps I am just overlooking it?
