The difference would be that 2fa and multifactor c
Post# of 82672
So the Iranians may be hacking (as can any hacker) the inband 2FA. Sadly most techies putting ads out trying to explain 2FA dont seem to know that there are inband and OOB methods of authentication. Consumers are also being mislead.
Also look up the court docs. posted on hangout and liehub. The court docs discuss the difference and even refer to SFOR's patent as "true out of band authentication" because there are so many misrepresentaion out on the market.
Hope this helps.
