OTP SMS: Many online web applications now require users to add an additional layer of security to their accounts.
This is accomplished by enabling two-factor authentication.
Two-factor authentication can be implemented in a variety of ways, one of which being TOTP (Time-based One-Time Password algorithm) authentication.
An OTP SMS is a password that is only valid for one login session, making it less vulnerable to replay attacks than a standard password.
Because OTPs are generated within an app on a user’s device rather than being sent through SMS, they are intrinsically more secure.
Users’ verification by mobile phone is required at this vital time. When it comes to decreasing suspicious activity, verification is extremely successful.
By ensuring that a captured user name/password pair cannot be used a second time, the OTP SMS feature helps to avoid some types of identity theft.
The user’s login name usually remains the same, while the one-time password varies with each login.
OTPs are one-time passwords that are only valid for a specific login session and for a specific amount of time.
Why is it vital to transmit an OTP SMS while logging into an app?
As the name implies, one-time password (OTP) solutions allow users to log on to a network or service using a unique password that can only be used once.
The static password is the most common and least secure authentication method. Only the owner of that phone number has access to that password, allowing them to log in to the app and authenticate their identity with an OTP SMS or PIN code.
This automatically produced OTP SMS is subsequently made available to the user via various transmission modes during download and password resetting in the application.
Data theft and password breach are less likely with the OTP-based login option.
How can OTP SMS help you reset your login password?
Sending an OTP through SMS to authenticate the user’s identification when a user signs in to an app or website from an unknown or alternative device (i.e. with a different IP address from the one recorded in their profile) and asks for a password reset can help decrease fraud and identity theft.
When a user of your app or website tries to sign in after a long period of inactivity, an OTP SMS can help confirm that the user is authentic and not a hacker or spammer.
An OTP SMS is used to avoid fraud by ensuring that the person logging into the app is the same person. To accomplish this, an SMS containing a temporary code is sent to the person’s phone number.
What factors should you consider while selecting a mass messaging partner?
An excellent message partner will be as concerned about your recipients as you are.
The following are some criteria to consider when selecting a Bulk SMS Service provider:
- Easy API: Sending bulk SMS to thousands of recipients must be useful. Your bulk SMS gateway supplier should supply you with a simple API or admin panel that quickly distributes SMS via its SMS gateway.
- Sure-shot SMS delivery: The ideal bulk SMS provider will have message re-routing in place so that each recipient receives the message no matter what.
- Your supplier will present you with a plethora of options for making business communication simple, smooth, productive, and cost-effective.
Now the few questions arise
Q. Is it possible to utilise the same OTP SMS for many transactions?
A. No. The One Time Password (OTP) will be issued automatically and quickly to the phone number and email address you provided when you installed the app.
Q. Is it possible for me to generate this One-Time Password (OTP) prior to the transaction?
A. No, each 6-digit OTP SMS is unique to that transaction and cannot be used for another.
Q. For how long is the OTP SMS valid?
A. Each OTP SMS is good for a few seconds or until it is used successfully, whichever comes first.
What is the purpose of OTP SMS?
The more permissions an app asks for, the more suspect it appears. However, issuing an OTP is critical for preventing fraud. As a result, applications that intercept OTPs for malevolent purposes appear to be less suspicious at first. The apps can read the OTPs that their own servers create. SMS messages with a unique alphanumeric code (hash) that relates the message to the app that generated the OTP are accessible to apps.
Even with a large number of codes and knowledge of when they were valid, determining what the key that generated them might be is nearly impossible.
Conclusion
Two-factor authentication is becoming increasingly prevalent. It is used by a large number of online apps for added security.
Unlike the SMS-based method, the TOTP method does not necessitate a significant amount of additional effort.
As a result, this functionality is worthwhile to have in any program.
