Verification Code

What Is a Verification Code?

A verification code is a security protection method that is used to avoid internet bots from abusing or even spamming various online services. 

If you've ever been prompted to solve a captcha when visiting a website and trying to fill out a form then you already know what this looks like. A captcha is a randomly generated code that appears as an image above a textbox. The site visitor needs to type the same code that appears in the image in order for the form data to be sent. Each time the form is accessed a different code will appear.

Captcha images are often a little difficult to decipher, even for a human, so as to prevent bots from being able to read them.

Aside from captcha images, another form of verification is a Google Verification code, which is a short numeric code that is sent directly to the user, typically through phone or email through which they verify their identity. 

Users may need to enter a verification code whenever they try to create an account on Google, reset their password, or log in from a different, unknown device to their accounts for the very first time.
