SMS You are both the sender of the token and the recipient of the message . SMS Also, by having the customer send the message, you will not have to pay. Still not clear? Follow the guide.
SMS OTP: How does it work?
SMS OTP is a message containing a short, unique code , usually 6-8 digits, used to authenticate a user . The user sms services enters the code into a web page or application to complete a login, registration, or validation process.
SMS On the platform or API side , the OTP is routed on a super-priority basis to ensure timely delivery of the temporary code it contains (an average duration of 1 minute).

Two-factor authentication (2FA) to validate the creation of an account, a transaction or a password reset.
Often used by banks through 3D-secure, this method ensures that the applicant has two distinct identification factors (a code they know and an object they own).

After entering their user ID and password, the user is prompted to provide a second applying the drive-to-store strategy with an sms form of identification from a separate device, such as a smartphone. This second factor can be a token or a text message sent to the user’s phone.
SMS A Money App Behind a Disruptive Model for Free OTPs
A French fintech startup has taken a new approach to two-factor authentication . SMS It has found a solution that allows it to reverse its authentication system by acting as an OTP receiver , thus eliminating the need to send .
SMSIn practice, the startup rents a virtual mobile number to receive . SMS Its users themselves send an OTP generated in-app, to validate a transaction. This OTP is generated by the customer directly in the application, to be sent to the Virtual Mobile Number (NVM ). SMS Once bw lists received, the application matches the generated OTP to the user’s phone number and validates the transaction.
SMS SMS In short, instead of sending an OTP to your customer, it is your customer who sends an OTP to a virtual phone number . The only cost associated with this authentication system is the rental of a virtual mobile number.
