Cal’s Apps 2FA Service works by you creating a free account, logging in, and creating a 2FA Screen. You then get simple instructions on how to implement the service on your website! This service comes in handy when you need to verify an email address by automatically sending an email to the client’s address.
Generates a secure 6-digit code and emails it from 2FA-Service@calsapps.com.
Your site calls an API endpoint, receives a code, then asks the user to type it in.
Create screens (domain + name), get a screen_id, and start sending codes.
