Botdelive: 2FA and Push via chatbots!

Greetings ProductHunt! We've just launched our product called BotDelive. Botdelive is 2FA and Push Notification service for websites and apps. The generic 2FA solutions offers; SMS, E-mail or 3rd apps. But... 1. SMS are not the secured way to get the important keys to access private accounts. Beside of security, If the user changes device or phone number, developers have to ask for the updated phone number again. 2. E-mail is secured but the not reliable way. The important message could be flagged as spam by the e-mail providers. 3. 3rd 2FA apps require to be installed. These apps are using the memory of your devices. Sometimes they don't work as expected. But, what if we can use the chat apps? They're already installed to billions of devices and they're reliable! BotDelive solving this kind of problems and offers 2FA and Push Notification solutions. We're in beta right now but would like to hear your comments about our lovely product.
