In the age of increasing cyber-crime and incidents of user data theft, it has become crucial for companies to implement powerful data security mechanisms. Hence, many companies, such as Google and Facebook, have installed two-step authentication on their websites to protect their users against unauthorized logins to their accounts, and the OTP SMS technology has made this very easy.

What Is OTP SMS?

OTP, or One-Time Password, SMS is a short message containing a one-time auto-generated password that is sent to the registered mobile phone number of the user who has initiated the request. This technology is perhaps the most popular mechanism used by companies around the world to make sure that the login request has been generated by an authorized person. It is very simple to use the OTP SMS service.

As soon as a user enters their username and password to log in, OTP SMS is sent on their mobile phones. This SMS contains a code, usually four to six digits and valid for only one-time use, and the users are required to enter this code as quickly as possible (in most cases, the OTP expires within a minute and the user has to generate a new one) into the given space in order to proceed with the login. This way, it is ensured that the person, logging into his/her account is authorized by the account holder, to gain access to it.

Who Needs OTP?

Online identity theft has become a huge issue around the world, especially since users have started maintaining sensitive personal information on the web. As many as 15 million people in the US fall prey to online cyber-attacks every year, which results in a cumulative loss of around $50 billion. Statistically speaking, this puts over 100 million people in the US at risk of losing their data.

Hence, enabling the OTP SMS verification process offers additional protection to users from hackers when they login to a website. If you are running a website that stores sensitive user information, it is wise to use the OTP SMS verification technology as it is very cheap and offers additional security to your account holders.

Your customers are the biggest beneficiaries of the OTP technology, as they feel more confident that their data is secure and well-protected against hackers. But, your business benefits from the OTP technology as well. Having two-step authentication on your website shows your customers that you care about protecting their personal information. Also, since the entire OTP SMS verification process takes only a few seconds to complete, it does not cause users any inconvenience when they log in.

Examples Of OTP

Although the OTP SMS verification is still optional for some online services, many have installed it as a default step during the login process, especially those businesses that conduct extremely sensitive operations for the users such as online payment portals operated by banks and other financial service providers, email services like Gmail, social media platforms like Facebook, and e-commerce platforms like Amazon.

In fact, whenever someone conducts an online transaction and uses their credit/debit card, the card provider usually sends the cardholder an OTP SMS to verify the transaction request before processing it.

Gmail SMS OTP Verification

Google encourages its Gmail customers to use the two-step OTP verification provided by the service on their email account to prevent unauthorized access to it. The OTP service is both fast and free to use. As soon as users log in to their Gmail account from an unauthorized device, an OTP SMS is sent to their mobile phone which users need to enter in order to access their account. According to Google, it is very easy for account passwords to be stolen, hence OTP is necessary to protect against such incidents.

Facebook OTP SMS Verification

Although Facebook does not mandate OTP SMS verification for its users, it is still recommended. Users can provide their registered mobile phone number to Facebook and enable two-step verification. Then, when they log in, the social media platform will prompt them to enter an OTP that will be sent to their mobile phone. Facebook uses a six-digit OTP code. In case the code is not received, users can also send an SMS to 32665 to receive the OTP SMS for free.

Amazon OTP Text Message

Amazon uses OTP text messages as part of its two-step verification process when customers log in to access Amazon’s services. Customers may also choose to receive their OTP through a voice call or with an Amazon authenticator app. Since many customers use their personal devices to log in, Amazon allows the option to register devices so that an OTP is not required every time a user logs in.

Some devices offered by Amazon also require OTP authentication, although they do not redirect to another page where the OTP may be entered. In that case, Amazon requires customers to log in on their device once, which gives them an error message saying that either the username and/or the password is incorrect while Amazon sends an OTP to the user’s mobile phone. Then, customers are required to sign-in again, using their Amazon username and password and also add the OTP code at the end of their account password.
