Hi, We are looking to implement 2FA - so that users would be sent a Verification code over their Email and SMS to their phone.

We faced some limitations with Amazon SNS where we could either send the verification code to email OR to the phone number, while we want to send it to both.

We also are looking to make the 2FA more flexible by adding any other options later on.

What are the best alternatives to SNS for this use case and purpose? Looked at Twilio but want to explore other options before making a decision.

Would be great to know what the experience with Twilio has been, especially the limitations/issues with Twilio...

Appreciate any input from users of Twilio and others who have had similar use cases.

Hi, Stackshare community, I plan to build an app where people can go live, and users can watch him, 1 to many, follow each other, and text.

I am expecting a huge number of users to use the app in the first month (100k+)

I made the UX/UI design, and my designer asked me to find a developer.

I want your advice. What server is the best for video quality and fast text messages (like uplive, bigo)?

Ex. Agora, Twilio, Amazon Chime, Aws, or fiberbass

I need for both operating systems, (ios, android). Do you recommend Flutter?

  • I have AWS server in my country (Bahrain), and 80% of the audience are from the same area. Does it help in the video quality between the audience?

Thank you for this helpful website.
