FAQs
What is SMS two-factor authentication (2FA)
SMS two-factor authentication (also called 2FA SMS) is a security method that uses SMS to send a one-time code (OTP) to verify a user’s identity. It’s often used for login protection or secure transactions.
With Kudosity, you can integrate SMS 2FA to your platform using our secure and reliable OTP SMS service.
How does 2FA via SMS work?
2FA using SMS works by sending a one-time password (OTP) to the user’s phone after they enter their login credentials. This second step confirms their identity and prevents unauthorised access.
