OTP Code

OTP and Its Applications

An OTP is a numeric or alphanumeric code used as an additional security measure during logins or transaction confirmations. Its purpose is to ensure that the individual accessing an account or conducting a transaction is the legitimate owner. OTPs are typically sent through text messages (SMS) to the user's registered mobile number. They serve as an added layer of protection against unauthorized access and fraudulent activities.

Generating OTP Codes

  1. Requesting OTP: When a user initiates a login or transaction, the system prompts them to provide their registered mobile number or email address.
  2. Code Generation: The system then generates a unique OTP code associated with the user or transaction.
  3. Delivery: The OTP code is securely sent to the user via SMS, email, or through a dedicated mobile application.
  4. Validity Period: OTP codes have a limited lifespan, typically ranging from a few minutes to several hours, depending on the service provider's configuration.
  5. Input and Verification: The user is prompted to enter the OTP code into the relevant field on the login or transaction page. The system verifies the code's accuracy and validity.
  6. Access Granted or Denied: If the OTP code matches the one generated by the system and is within the valid timeframe, access to the account or completion of the transaction is allowed. Otherwise, access is denied.
