Use case: SMS voor 2FA (Tweestapsverificatie)

To add an extra layer of security to the banking process, the Bank of Breda uses Smstools software. They use SMS messages for two-factor authentication (2FA) and one-time passwords (OTP).

Two-factor authentication '2FA' based on one-time passwords (OTP)
The Bank of Breda uses 2FA to log customers into the secure area for online banking. For extra security, they send a code or one-time password through SMS. The customer must enter this code or password to identify themselves. Thus, in addition to the traditional security (username + password), there is an additional layer of protection linked to the code that one can only receive if one is also in possession of the cell phone.
Two-factor authentication makes it much more difficult for criminals or fraudsters to log into accounts that do not belong to them. These criminals must also receive the SMS message with the code and the username and password.
