I am a solopreneur / freelancer who is looking to replace the way we do authentication for transactions via SMS OTPs (save money in return) and I need your opinion on it.
I am working on a service which will allow you to use missed calls as a medium for 2FA, verify mobile numbers for COD, voting etc. without you shelling a lot per month and with full control over your phone number (unlike those missed call services where you don't have access to your own number and it gets reassigned to someone else later).
I am still in development phase and would like your inputs. For this purpose I have created a questionnaire. Everyone who is going to give their valuable opinion will get 3 months free subscription to the plan when I release it. Just don't forget to enter your name and email at the end. Thanks for your help, in advance.
Here is the link to the google doc form: https://goo.gl/forms/DidEOF5701RXkUSF2 If you think that it is too long, then please write your opinion as to you would like to use this kind of product/service here itself.
