What is OTP？

OTP stands for One-Time Password, which is a method of using single-use passwords for identity verification. Each time a user logs in or performs sensitive operations, the system generates a new password that can only be used for that specific session, ensuring user security and privacy.OTP verification codes are generated by the system and then sent to users through various means such as SMS, phone calls, email, or mobile applications. Upon receiving the OTP verification code, users must use it within a certain timeframe, as the password becomes invalid after that period. This effectively prevents phishing attacks, password cracking, and other security issues, thereby enhancing the security of user accounts.

The importance of OTP verification code

As internet usage becomes increasingly widespread, users' personal information is more vulnerable to attacks. Traditional password authentication methods are no longer sufficient to meet modern security needs, as passwords are susceptible to being cracked or stolen. However, with the implementation of OTP verification codes, which use one-time passwords, the risk of passwords being stolen or compromised can be effectively mitigated, thus enhancing user security and privacy. Moreover, OTP verification codes also help prevent phishing attacks and social engineering attacks. Phishing attacks involve deceiving users into disclosing their passwords or personal information, while social engineering attacks exploit human psychology in order to manipulate individuals. OTP verification codes can effectively thwart these attacks, further bolstering the security of user accounts.

Application of OTP SMS and Voice Verification Code

With the continuous advancement of internet technology, online scams and fraudulent activities have become increasingly sophisticated. To safeguard user information and enhance security measures, more and more websites and their membership systems are adopting verification code technology. Among these, OTP SMS and Voice Verification Code are the two most common methods used.

OTP SMS

In the website membership system, you need to implement the OTP SMS verification functionality by integrating an OTP SMS verification API. You can use existing OTP SMS verification services such as Twilio or AboSEND, offers a secure and widely applicable method. By delivering the OTP code via automated voice calls, it ensures a higher level of security, especially in industries with strict security requirements like finance, healthcare, and government agencies. The method is resistant to interception as it doesn't rely on internet connectivity.

Voice Verification Code

Voice-based OTP verification, using an IVR system like AboTalk, offers a secure and widely applicable method. By delivering the OTP code via automated voice calls, it ensures a higher level of security, especially in industries with strict security requirements like finance, healthcare, and government agencies. The method is resistant to interception as it doesn't rely on internet connectivity.

The differences between Voice Verification Code and OTP SMS Verification

Voice Verification Code and OTP SMS Verification are both common methods of identity verification

	Voice Verification Code	OTP SMS

Conclusion

OTP verification code is a secure identity verification technology that effectively protects user security and privacy. Using OTP verification codes can prevent phishing attacks, password cracking, and other security issues, thereby enhancing user account security.
