I never needed or thought about a utility to authenticate anything till I took advantage of a free cloud service with a mega cool 50 gigs storage...until I put it on my iPhone 8 and the cloud service required me to have an app to authenticate my account. This was the only such thing to surface from the App Store and lucky lucky, easy to use, just pop in the 6 digits it gives you and it’s done. Used it to send hour long psychedelic jazznotic jams mixed from multi track to band members of The Taken. Me No shame wha??? No adds, no annoying nuthin! Nice to know good people are making good thing’s just more doable. Very cool bit of utility in my opinion. Thanks to the developer hope more will follow your example. ## Frequently asked questions about Mobile OTP Authenticator ### How do I add an account to Mobile OTP Authenticator?
