How to use Smstools for my 2FA messages?

What are 2FA messages?

2FA messages, or two-factor authentication messages, are short SMS messages sent to a user's mobile device as part of the two-step verification process for securing online accounts. They contain a unique, temporary code that the user must enter along with their password to gain access, providing an additional layer of security.

What do I need to implement 2FA in my website?

To set up 2FA (Two-Factor Authentication) on your website using the Smstools platform , you'll need to follow these steps:

Register and Set Up an Account on smstools.com:
Sign up for an account on smstools.com.
Obtain your API key and other necessary credentials from the smstools.com dashboard.

Integrate SMS API into Your Website:
Use the API documentation to integrate the SMS sending functionality into your website.
This typically involves making HTTP requests to the SMS service with necessary parameters like phone number and message content.

Set Up a Backend to Handle 2FA Logic:
Generate a Verification Code: Create a function to generate a random verification code. This can be a 6-digit number.
Store the Code Temporarily: Save the generated code in a temporary storage, like a database or in-memory store, along with the user's identifier and a timestamp.

Send the Verification Code via SMS:
When a user initiates the login process, generate the verification code and send it to the user's registered mobile number using smstools.com's API.

Create a Verification Endpoint:
Provide an endpoint for the user to submit the received verification code.
Upon receiving the code, check if it matches the code stored in your database for that user and ensure it hasn't expired.

Grant Access if Verification is Successful:
If the code is correct and valid, complete the login process and grant access to the user.
If the code is incorrect or expired, prompt the user to try again or resend the code.

Optional fail-over via VOICE

Add a backup solution to the login webpage via Voice.
Eg: the end-user can click "message not received" and it will trigger a VOICE call instead of an SMS.
The voice mesage will send a spoken voice message with text to speech technology.
