When we access a site or blog in the Internet era today, we are frequently prompted to register only if we are qualified to access the website’s content after registering. Consequently, we must register our phone number and address with an OTP on these websites. If you aren’t already aware, an OTP or one-time passcode is a 2 factor authentication method. This is an authentication code that can only be used once to authenticate to your account. It is usually sent via email, SMS text, or third-part authentication application. 

Yes, you can divert OTP to another number as well. There are a few steps to do it which have been given:-

  1. Using an SMS forwarding option
  2. Using a virtual mobile number
  3. Giving another option for OTP

This article will explain how can you divert OTP to another number. Furthermore, this article will elaborate on how hackers exploit this vulnerability to their advantage by sending random OTP’s to the victim’s phones or by using SMS forwarding. 

What Is An OTP (One-Time Password)?

A one-time password (OTP) seems to be a string of randomly generated alphanumeric or numeric characters that verifies a user for a single exchange or login session.

A one-time password (OTP) is safer than a stable password, particularly a user-created password that may be weak and/or repeated across several accounts.

OTP may replace or be used in conjunction with authenticating login information to offer an additional degree of protection. OTP servers as the second layer of protection for the user.

OTP security codes are working like smart cards or key fobs that generate an alphanumeric or numeric code for system or transaction authentication. This code varies each either 30 or 60 seconds, based on the settings of the token.

Apps for mobile devices, including Google Authenticator, use the token and PIN to produce the one-time passcode for multiple verifications.

Tokens for one-time password authentication (OTP) can be handled using hardware, software, or on-demand. The one-time login is used for only one transaction as well as a login session, unlike standard passwords which are static or expire between 30 and 60 seconds.

How To Obtain A Single-Use Password?

Authentication management on the network server creates a unique number or shared secret using one-time password methods when an unverified user seeks to access a system or complete a transaction on such a device. 

The security token just on the card reader or device uses the same number plus algorithm to confirm the one-time passcode and user.

As a second authentication step, many businesses employ Short Message Service (SMS) to send a provisional passcode through text message. 

After entering his password and username on connected information management and transaction-oriented online apps, the user obtains the temporary passcode via off-band cellular conversations.

To access an account or system using two-factor verification (2FA), the user must input his user ID, conventional password, and temporary passcode.

One may also begin to receive numerous SMS/messages/notifications that are needless. Everyone becomes annoyed by it.

The Operation Of A One-Time Password

OTP-based authentication solutions rely on shared secrets between the user’s OTP app as well as the authentication system.

By using Hashed Message Authentication Method (HMAC) technique plus a moving factor, such as time-based knowledge (TOTP) or an event counter, one-time password values are created (HOTP).

For further security, the OTP values contain minute or second timestamps. The one-time password may be sent to a user via many channels, including SMS, email, or a specialized program on the endpoint.

Security experts have long feared that SMS message faking and man-in-the-middle (MITM) assaults can be exploited to compromise two-factor authentication systems that rely on one-time credentials. 

Nevertheless, the U.S. National Standards and Technology Institute (NIST) has announced intentions to deprecate the usage of SMS for two-factor authentication (2FA) and one-time passwords (1TP).

This is due to the method’s susceptibility to a variety of attacks that might compromise passwords and codes. Therefore, businesses contemplating the use of one-time credentials should investigate alternative transmission mechanisms besides SMS.

Advantages Of One-Time Passwords

The one-time password overcomes major password security issues encountered by IT administrators or security managers. 

They should not worry about designed networks, known-bad or weak passwords, credential sharing, or reusing the same password across many accounts and platforms.

Another benefit of one-time passwords would be that they expire within minutes, preventing attackers from gaining and reusing the secret information.

How To Verify OTP Without A Mobile Number?

To validate or circumvent SMS or OTP, some websites provide throwaway phone numbers. If creating an account on a site or app requires SMS verification, you can use the throwaway phone number. 

This allows you to avoid disclosing your telephone number. No registration is required to utilize this website. And so this service is provided without charge.

When you establish an account on a website and mobile app or attempt to log in, an OTP is given to your phone. This OTP must be input into the mobile/application.

To get OTP, a cellphone number is required. The OTP will be issued to your phone through SMS. Therefore, a temporary cellphone number is required. 

If you believed you could avoid cyber threats by exercising caution when using the Internet, not sharing important information with others, and avoiding clicking on links in unwanted spam emails, you are mistaken. 

Hackers have discovered a new method of obtaining personal details, including one-time passcode (OTPs) or login information for applications such as WhatsApp.

Utilizing text-messaging management services designed for companies, hackers reroute SMS messages intended for victims to their systems. Such assaults are caused by the incompetence of telecom corporations in nations such as the United States.

According to a story, journalist Joseph Cox fell victim to an assault on his contact phone. Cox’s SMS messages were redirected, while his WhatsApp, Bumble, and Postmates identities got hijacked. 

The hacker was able to access his accounts and get images of their content. Fortunately, the assault was conducted by the anonymous hacker Lucky225 under Cox’s consent in order to expose the vulnerability.

In contrast to SIM swapping or SS7 assaults, which also target SMS and cellular networks, the victim will not instantly realize whether his or her messages are being misdirected. 

When OTP SMS’s are not received, it is simple to believe that there is a problem with the connection or service provider. 

In SIM swapping or SS7 assaults, the victim realizes within a few seconds that his or her phone has been compromised since it loses all cellular network connectivity.

The SMS redirection service is available for use. The service is intended for companies, but hackers are abusing it. 

In most instances, service providers do not ask for the user’s consent before redirecting text messages; they just tell the owner that the messages have been forwarded.

Using these services, hackers may quickly reset the passwords of your accounts, and you may never be able to access them again. Therefore, the next time you do not receive your OTP, investigate the cause.

How To Receive Someone Else’s Text Messages On Your Phone?

In addition to SMS, spyware applications may enable you to monitor your loved ones’ social media or email messages. Several spy programs enable you to access your spouse, kid, and employee’s instant messaging conversations on all active platforms. 

WhatsApp, Facebook, Snapchat, Instagram, Facebook Messenger, and Skype are examples of social media applications that may be monitored. With mobile phone spyware, you may monitor the target smartphone’s sent and collected text messages and multimedia data.

Additionally, you may examine communications that have been deleted from your spouse or child’s mobile phone. This function allows you to observe the Snapchat conversations of your close friends after they have vanished. What’s interesting is a lot of “spyware” is actually legitimate child monitoring software used to control content searches, usage times and more. What’s worse is that the bad guys will abuse this software for unauthorized purposes intended to steal data or spy on victims.

Other Methods Of Forwarding Messages To A Different Number

SMS is used to interact with nearly everyone, including employers, intimate partners, and close family. Thus, you may learn a great deal about someone’s private life simply by reading their text messages.

Android users, for instance, might utilize the SMS Forwarding smartphone app. You may install the app on the reference smartphone by downloading it from the Google Play Store.

In the digital age, text messages are among the most effective forms of communication. Therefore, even establishing the SMS Forwarding program is simple and should take no more than a few minutes. 

Once the software has been properly installed, it will forward every SMS from the target device to your mobile number. If you like, you may also have the SMS forwarded to your email address.

However, this strategy is not as discreet as the eavesdropping options provided by the spy software. As a result, you will not be able to see your family members in private mode and it may ultimately be discovered.

Conclusion

If you’ve been searching the Internet for information on how to divert OTP to another phone, it is recommended to use monitoring applications to pass text messages to some other phone without anyone knowing. Of course it is implied, but never do this type of action without the explicit permission from the device’s owner. You may be held criminally, legally, and financially liable for damages if perform actions like this unethically.

These software solutions provide complete stealth mode surveillance, so you will never be discovered. Android users may also access the SMS of their loved ones with the SMS forwarding application.

Lastly, virtual phone numbers can also be utilized and many online websites provide these services free of cost which are in turn used by hackers for malicious purposes.
