 use, never share this SMS or code with anyone.

You must have received this message while making a transaction, adding a beneficiary, or simply using an app or a service that requires a password for verification. Your bank also keeps reminding you not to share your OTP code with anyone.

Why is that so? What is an OTP code, and why is it used? If you are also curious to know about it all, keep on reading.

What is an OTP Code?

OTP (One-time PIN) or OTAC (One-time authorization code) is a password used only once. It is a feature of 2FA (Two-factor authentication) security. Whenever you attempt to access a service, you will get an OTP on your phone, and you must submit it to confirm your identity. Not to mention, you can use this as your status password, and it is supposed to be used once; after the use and a limited period of time, it becomes invalid, and the process must be started again.

How does OTP work?

When logging into their digital accounts, an OTP code is sent to the User’s registered mobile device. It is a verification process, and once the code is entered and access is granted, the pin expires at the very moment.

Usually, the code is a four or six-digit numeric PIN or, in some cases, a combination of characters. Having said that, you can get the code on your email address as well. For additional security, some banks sent one part of the code to the registered mobile address and the other part to the email.

OTP code not only saves you from internet scams but also gives a sense of satisfaction that the financial transactions are safe and secure. If someone is trying to get into your digital account, you will receive an OTP code on your registered account without entering it; the scam won’t be possible, which is why you should never share your OTP with anyone, not even with the bank’s representative. The codes are generated via a random algorithm, which creates a new password every time.

Benefits of OTP Code:

OTP codes offer several benefits, especially in a country like Pakistan; they ensure that transactions are secure, which is important due to the rise in digitalization and online transactions. Let’s explore some of the benefits of OTP’s.

1. Enhanced Security:

OTPs offer numerous benefits to cover as we switch to dynamic password protocols. Users face severe cyber threats like Phishing attacks and thieves of ID; OTPs are an irreplaceable part of cyber security because they require dynamic code that changes with each attempt to log in or make transactions. It implies the User’s static password, if stolen, needs to be more. The attacker would also need the special OTP; thus, the risk of solely relying on OTP is low.

2. Protection Against Identity Theft:

Identity theft is as big a concern for the people of Pakistan as there have been cases of compromised information on their personal details. OTPs provide protection against such theft because of their time-sensitive nature and the expired use immediately after a single use. This impedes the effort of the swindlers to recycle the credentials they’ve stolen in order to gain access to accounts. In this way, they are not able to trick someone into making a fraudulent transaction.

3. Secure Online Transactions:

With the advancement of e-commerce, safe transactions are of the essence in order to prevent consumers from losing trust in online businesses. OTPs bring great significance here as they ensure transaction safety by identifying the user during the payment operation. A one-time-password scheme (OTP) serves as a multi-pronged security measure that helps prevent online fraud and account takeover even if a customer has fallen victim to the activities, such as making purchases, transferring funds, and other financial transactions online, which require an additional security method.

4. Compliance with Regulatory Requirements:

Regulating bodies in Pakistan including the State Bank of Pakistan (SBP) acted to develop the standards and requirements to implement the secure transactions and protection of customers with their financial details. This OTP implementation can aid businesses and financial services companies as a whole in abiding by these regulations by adding more delivery measures to their systems. It does not only assist in complying with data protection laws but also evidences the fact that data security and safeguarding trust are among the founder principles of the financial system.

5. User Convenience:

Owning to the fact that mobile phones are used widely and one can get an SMS-based OTP through his/her mobile device, the users can receive verification codes easily, and actually, they do not have to be loaded with either hardware tokens or complex authentication methods. As a common identification system, cryptographically strikes a balance between security and usability conditions.

6. Adaptability to Different Platforms:

OTPs can be applied to practically all types of machinery and devices regardless of the platforms that they use. They are specific for use in services and applications in the digital world. A variety of security applications for OTPs can be found in different sectors, whether it is e-banking, government services, or social media authentication, and the verification codes can be easily incorporated into existing systems to make them more resistant to breaches and other cybersecurity issues.


A one-time password (OTP) is a crucial tool that provides security to financial transactions. The digital landscape is evolving, and to combat cyber threats such as phishing, identity theft, and unauthorized access, OTPs play a vital role. In addition, it also enhances the confidence of the User in online transactions and ensures a balance between security and user convenience. As Pakistan continues its journey towards financial and digital transformations, OTP stands out as a security measure that protects sensitive information and provides protection to the overall digital ecosystem.

  1. How OTPs (one-time passwords) work?

OTP is a dynamic code consisting of numeric and characters that can be recreated only once and need to be validated instantly to be effective. In addition to this, it is most often used by users as one of the authentication factors to process online transactions, and account logins among others as a way of verifying their identities.

  1. How does the OTP (one-time password) work?

When the User starts initiating a transaction or login, the system requires the User to enter the OTP before this can proceed successfully. This OTP means the system will generate and send the OTP to the User via mobile messaging service, email, or authenticator application. When submitted, the user types in this OTP at the spot during the timeframe to authenticate their identity. OTPs are only valid for a specific amount of time and should be used once only; hence, if someone else has access, they cannot use this technique anymore.

  1. What are the reasons for using OTPs in security?

OTP is a necessary tool because it helps to combat the attack of identity theft and any other unauthorized access. Unlike conventional static passwords, OTPs are no longer one-time passwords that at one point in time are dynamic and expire after an operation is complete, thus posing a bigger challenge for cybercriminals. Through the compulsion of users to supply OTPs in each transaction or login attempt, OTPs make the security levels high and secure the personal data from cyber-attacks such as phishing scams or theft of credentials.
