As a cellphone owner, you must have received text messages sent from apps or websites with a digital code, to verify your identity. This verifying method has already been quite common all around the world.
What is a verification code?
A verification code normally contains a series of 4-6 digits. It is sent by text messages. People receive the code on their mobile phones. Verification codes are often mostly for identity verification.
Why do we need verification?
The merchants want valid users. A valid mobile phone number could prove the user is real since a valid mobile phone could receive a verification code.
It is also essential to verify the users’ identity when they activate sensitive activities, such as making payments or downloading sensitive files.
Many merchants have adopted this method for their businesses. Text messages are very cost-friendly. At the same time, they are very effective. A small budget could solve a big problem.
How does the verification code work?
The code sent is triggered by the user’s activity. The user receives the code and is required to input it on the website or the app, and the system will approve the user’s activity after receiving the code.
2 Factors Authentication (2FA)
