Also called two-factor authentication (2FA) based on an SMS verification code or one-time password (OTP), SMS verification is an essential way to double-verify the identity of a user when he or she uses a website service, or application, bank account, and social network. With a username and password provided, an SMS verification code will be also sent to a phone number owned by the user so that the login will be completed after two-factor authentication.

Undoubtedly, easiness and convenience lead SMS verification to be a leading way to verify the validity of an online user. Recent years have witnessed SMS verification be accepted by online users and customers due to its convenience and simplicity.

Sounds familiar?

Although SMS verification is being widely used on most websites or applications, it still features both pros and cons.


Security has its own relative independent ability and the security here refers to that when compared with a password. A password is stable and tends to be easily stolen. An SMS verification is active and it only works within a limited time. Even though it gets stolen, the account may still be well protected if it goes beyond the code “shelf life”.


SMS verification is so simple that the whole process costs just as little as a couple of seconds. Service providers, they don’t need to worry that potential will possibly give up registration because of the lack of a tool. After all, everyone has a smartphone, even a phone.

Everything is risky when it comes to the internet. It’s equivalently risky for the SMS verification system to be hacked. Whenever that occurs, the verification will be dangerous.

What if a Smartphone Gets Lost?

Once a smartphone is lost, SMS verification will be risky if your private phone number is used.

Sync Devices

Where to get a second phone number, then?

The best place to find an extra number is a second phone number app. There’s no need to get a second smartphone or SIM card but what you really need is just a number alone. A second number is needed to receive the SMS verification code and it should be a valid real number with a true area code and full digits.

Everything is relatively secure in the current world where everything connects, including SMS verification. However, it’s been widely used as a top way to verify a user’s identity, which has been proved it’s the most secure and reliable.

First, ensure whether the number you provided is valid to receive the SMS verification code. After all, not all phone numbers can help to pass the SMS verification code.

Then, you should check whether the phone number has already been linked to another account on this website or application. If it’s been used by anyone else, it won’t work again.

Next, if the number doesn’t belong to the above two conditions but you still failed to receive the SMS verification code, you can either wait a couple of minutes or consult with your number carrier. Sometimes, it’s the network that stops SMS verification code from arriving in time, and waiting a couple of minutes may be a good idea.
