In every digital payment or lost password reset, a one-time password, or OTP, is one of the most important factors. It is really aggravating when OTP is not received. Despite the fact that also had similar difficulty, I had not gotten my OTP for quite some time.

Yes, there are instances when your OTP is not working. You can adopt one of the following measures in order to cope with this sort of problem:

  • Reset the device 
  • Reset the network configuration
  • Check your mobile network
  • Verify if your SIM card is working properly

This article will elaborate on and explain what can a person do if the OTP is not working. Furthermore, the possible ways and methods of making an OTP work will also be discussed in detail.  

What Is A One-Time Password (OTP)?

If you own a smartphone, you are familiar with the acronym OTP. One Time Password, or OTP, is the PIN code that use to access your user account by way of two factor authentication (2FA). If you aren’t familiar, 2FA is an additional layer of authentication a user is required to provide in order to access his/her account.

When you are logged in, a dialogue box titled “Enter the OTP obtained from Google” appears after you have entered your PIN. Occasionally, though, you receive an “OTP not received” warning. 

Receiving an OTP is required when making online payments or resetting a very useful piece of information (provided you have set up 2FA on said account). It’s a security challenge of sorts. Similar to Google, Google has a captcha that checks whether you are a person or a bot utilizing their services. This helps to cut down on fraudulent requests for information. Captchas are complicated to bypass but they can be, nonetheless.

If indeed the OTP has not been received, try clearing the SMS app’s cache. Refresh the smartphone or reset the network configuration if the first two solutions do not work. 

However, OTP is not dependent exclusively on the device. The one-time password is also determined by the sender. Occasionally, brands or senders may not transmit the OTP.

A significant number of online transactions completed on mobile networks today do not require a One-Time Password from the user. 

While some customers face difficulties with these transactions since their OTP was not obtained, after entering the required information and reaching an agreement, the person’s OTP is required to access and finish some trustworthy transaction source. 

This may be necessary when entering into an agreement with a commercial bank, registering for your chosen social media accounts, or registering for a new website.

What Are The Issues With OTP?

It is anticipated that the vast majority of Android users are aware of the Google Captcha authentication process, which is seldom used to validate the user executing a job on certain websites when a networking breach is identified by Google software. 

An example is intended to resolve security concerns and determine if a person or robot is conducting the search. 

A One-Time Password is utilized to confirm and execute a digital transaction between two parties. This is often transmitted through SMS or email with varying-length passwords.

You may have completed a transaction with just an OTP Not Delivered, or perhaps have been unable to get an OTP for quite some time. This also resonated with me.

However, I was able to proceed with the help of straightforward instructions when I did not receive an OTP on my registration cellphone number. These instructions will offer you a general idea of what to do if you have an issue regarding OTP not being received.

What Are Issues With The Amazon OTP?

Amazon is among the most prominent and commonly utilized eCommerce platforms worldwide. Amazon is trusted by millions of users to purchase and sell things online. It has introduced a new safety mechanism for its clients.

Two-factor authentication is a login security feature of the system. Amazon requires you to submit a one-time passcode (OTP) to authenticate your account ownership before enabling you to log in.

If you have activated two-factor verification for your account and are using a new device, this will often occur. 

Occasionally, if OTP verification is not working, the security function may cause problems for many users. You can adopt the following measures if the Amazon OTP does not work:-

Repeat Your Submission Of The Code

If the password is not functioning, Amazon suggests emptying the cache of your browser. Clearing the browser’s cache is a straightforward operation. If the Amazon OTP is not working, Amazon suggests resubmitting the code. 

It’s not always a great idea, though. You have a limited number of attempts before Amazon freezes your login for 30 minutes.  We strongly suggest that you wait a few moments so that you may obtain a code and afterward attempt it. 

However, if you suspect you entered the code incorrectly, feel free to re-enter the code with the error repaired. If you’ve requested several codes, wait before trying again.

Amazon will only take recently-received vouchers if you have requested multiple copies out of irritation. They do not always come in the order you asked for, particularly if you have asked for numerous codes simultaneously.

In this situation, you may input an outdated code, which Amazon may refuse. If you wait ten to fifteen minutes before obtaining a new code, then may be able to check that the system doesn’t really confuse the two codes and that you input the proper one.

Try Another Browser Or Device

Simply sign in with a new internet browser or a new device if it does not work. If you are using a desktop pc, you can try the Amazon application on your mobile device or tablet.

If you have previously used these devices, you may not require an OTP; instead, you may place your order using your phone. By the moment you need to buy on Amazon next, any OTP-related difficulties may have been rectified.

If you do not get another device, you might try a different web browser. If you previously logged in with Google Chrome, try Firefox instead.

I Am Unable To Obtain OTP From One Particular Application

If you can send and receive standard text messages, your number is correctly set on our network, and the problem is with the app or website delivering the OTP messages. 

The best option, in our opinion, is to contact the app or website’s support team directly and alert them to the issue.

I Am Not Receiving OTP From Various Applications

A typical reason for this is the presence of an SMS blocker on your smartphone. Sometimes, the presence of SIM cards on different smartphones or cell phones is also an issue. Swap the SIMs or be done with the SMS blocker by removing it.

Once this is complete, re-request the OTP. If you are able to get the OTP on even a separate device, the issue may be caused by an SMS blocker on your device. 

You can also adopt methods to disable the SMS blocker. However, the instructions vary depending on your phone’s make and model. 

If, after 48 hours, you have not received the OTP on the alternative handset, please contact the relevant network operator and they will get you set up.

What To Do When OTP Is Not Received?

You can adopt the following measures in the case when an OTP is not received or the provided OTP is not working:-

Check Messaging Settings

For the majority of Android users, the smallest modification in device settings is typically unnoticeable. We all presume that the factory settings remain intact and unmodified at all times.

In contrast, routine checks must be conducted since these settings could have been modified automatically or manually.

For example, your network operator’s service center is essential for transmitting and receiving communications, including OTPs. It is quite confusing for users who appear to have altered this option however. 

The majority of consumers appear to organize the same numbers for their various sim card service centers, which ultimately proves ineffective. There are unique numbers for each mobile network service center.

A complete and current configuration is equivalent to receiving full and unimpeded communications. Getting any OTP for your smartphone is dependent only on the provider of the OTP and the technical capabilities of your Android smartphone. 

If this is not the result of a connectivity issue at the source, examine your message settings. This is the very first essential step to take if you are experiencing an OTP not received issue.

Filter Contacts

Contacts on a blacklist are incapable of sending OTP’s. It is also a prompt for individuals who have not got their OTP. 

You may be concerned about not obtaining OTP on the MTN and Glo networks, respectively. Have you reviewed your ban list? You may be shocked to identify the source of the OTP on your lengthy list.

The majority of consumers utilize the blacklist to weed out numbers that annoy them with unwanted calls. This is highly useful for dual-sim users. 

Unbeknownst to some, the blacklisted prevents the banned contact from also receiving the message on the Android smartphone.

Internal Storage Capacity

When the storage capacity of an Android smartphone reaches its limit, it typically malfunctions and performs less efficiently. Creating space by removing unnecessary files from the internal storage makes the system and applications more efficient.

Everyone has encountered a message that reads “Internal Storage is almost full, certain functionalities may not work properly” that appeared in the notification bar. 

During this period, the volume of messages that your devices will receive may be significantly reduced or jumbled. This is another way to prevent your Android device from obtaining OTP’s from external sources.

However, you may examine the contents of your device’s memory in great detail. Clear Messages stored data and any other data accumulations on your mobile devices. 

Network/Country Code

Incorrect network checks or country codes are still another cause of the OTP not delivered issue. Receiving an OTP also requires a solid and dependable Internet connection. 

Instances in which an OTP could not be located in your communications after several queries may need a network and connection test.

Occasionally, neither Airtel nor Vodafone will provide you with an OTP. Activate Flight Mode or reboot your Android smartphone to renew the network connection on your handset; then, if the issue remains, swap the SIM card slots. 

In terms of sim connectivity, iPhone issues with not getting the OTP are comparable to Android issues. For instance, the country code for Nigeria remains constant at +234. Ensure that no errors are made while entering your country code.

Empty Cache

I have frequently seen that due to cache data, the new OTP signals are not displayed since the old caching data is displayed.

Delete the cache to erase some files and information from the device. These may be transitory and are occasionally necessary while upgrading your smartphone or when the device is being upgraded. 

The clean cache button will delete all inactive data from your phone. Includes the information saved on the phone’s memory card and hard disc.

Therefore, if you do not receive an OTP, the messaging app’s cache may be to blame. To resolve the issue, long-press on the application > App Details > Storage > Clean Cache. Now you will receive the One-time password you requested.

Verify The Connection

We frequently believe that there is an issue on our end or with the Sender, and you do not receive a one-time password, so the connection should be verified first.

Reboot Phone

The primary offender in this scenario is the network extender. If you are unable to receive the OTP despite the fact that it has been transmitted, this issue may be caused by weak network signals. 

To resolve this problem and acquire a new OTP, you must switch your smartphone to airplane mode and restart it. When your smartphone restarts, disable the airplane mode and re-request an OTP; this time, you will receive the one-time password.

This is something I recommend for all those who are experiencing network issues, regardless of whether the 4G LTE sign is visible.

Check Your Telecom Arrangement

There is a policy among a select number of telecom firms. Without an active subscription on your sim, you will likely not get any one-time passwords. Even so, this is believable in other nations.

Consider that you are pondering why OTP cannot be received on Airtel and why OTP isn’t being received on jio/vi. First, determine whether or not you have had an active strategy of your own. Finally, reset the network

Do not worry when I instruct you to reboot the network. That only implies that you must reset your internet settings, which will reset your SMS default setup, internet configuration, and APN.

When you reset these settings, your existing network provider will install them instantly, or your sim will install them automatically, so you do not need to do any more steps following the reset. 

The Message Center Number system is a standardized method for numbering communications within an organization’s message center. 

It enables simple and rapid access to messages inside the message center. The Communication Center Numbering method is predicated on the notion that each message in the message center should be assigned a unique identifying number.

Reset The Network Configuration

The procedure of resetting mobile network settings is considerably more straightforward than it seems. Android’s mobile network options are accessible through the “settings” menu. 

To restore the mobile phone network settings, select “Additional Settings” and then scroll to the bottom screen.

You will find a Reset option. Tap this option then confirm your selection. Your device’s network settings will be reset and it will reboot. If you are still unable to connect, you should likely bring your smartphone to a service facility.

Reset the Date/Time

Android phones’ dates and times are regulated through the system settings. You may set your phone’s time and date to a specified day and time, or you can set it to the current timezone and date. Restarting the time will result in the proper date being shown.

If the Android smartphone indicates that updates are available, be careful to install them promptly. Although it may seem prudent to delay updating your operating system, doing so might potentially resolve flaws and faults you were unaware of. 

Recent research indicated that just 1 percent of the more than 1 million applications available through the Google Play Store had been updated after their initial release.

Conclusion

In the light of arguments stated above, it can be reasonably deduced that an OTP that is not working or an OTP that is not received has become a commonplace issue. Therefore, it needs to be properly addressed.

There are a number of ways through which you can ensure that OTP works or you receive an OTP within a specific time. Some of these methods have been provided as aforesaid. 

These above-mentioned steps will assist you in effectively resolving your OTP’s issues. You must know why the OTP is not being sent to the mobile device. Contact your network provider and manufacturing manager if the problem persists.
