language agnostic - Text message (SMS) verification for signups -


I have seen a troubled trend where websites need verification sent to cell phones by text message (SMS). Gmail and Facebook are two of them What should I know:

  1. Is it a good idea to start a cellphone instead of email now?
  2. How can I do this on my website?

Edit

I have some new questions on the subject in response to the answer:

  1. It seems that most of you are saying that SMS registration is okay. But what about those who do not have a cell phone? And why is it accepted to give your cell phone information independently?
  2. Do those big providers actually pay per message in a gateway service? Is it not possible to set up a server with the correct SMS software, or it is not possible to buy a subscription directly rather than at least a middleman?

    3. Most SMS Gateway Services have no type of API, an HTTP interface is considered ideal .

    Just make sure that you sign up for the service that allows messages to be received, because not everyone does it more for them because they have to send some types of data back to you. .

    Some services also send receipts, allowing you to see that the receiver has received an SMS.

    Some

    4. Regarding the question number 1, I think the commander Keane's advice is correct.
