Verification by SMS is a popular method of verifying the identity of users before they can access websites, applications and services. It can also be used to authenticate mobile numbers for payment and other purposes. Many businesses and services are now using WhatsApp for their verification needs, as it is a secure, convenient and cost-effective way of verifying users.
WhatsApp provides two-factor authentication that requires a user to enter both a password and verify their phone number before they can access their account. It also allows users to quickly send code-based messages to each other for verification purposes. This makes it a great option for companies that need to verify the identities of their customers quickly and securely.
The advantage of using WhatsApp for SMS verification is that you don’t have to pay any fees or sign up with an external provider like Twilio or Nexmo in order to use it. All you need is an active WhatsApp account, which most people already have. The process is simple: you send a code via WhatsApp, the user enters the code on your website or application, and then they are verified.
Another great benefit of using WhatsApp for SMS verification is that it is extremely reliable. Messages are sent almost immediately, so users don’t have to wait long periods of time before they can access your website or application after verifying their identity. Additionally, WhatsApp uses encryption technology which ensures that messages are secure when sent over the internet.
Using WhatsApp for SMS verification has some downsides as well. For one thing, it does not always work with all countries due to local regulations regarding messaging services like WhatsApp. Additionally, if your website or application requires more than just a code-based message for verification (e.g., an email address or phone number), then you may need to use an external provider like Twilio or Nexmo in order to get the job done.
Conclusion:
In conclusion, using WhatsApp for SMS verification can be a secure, convenient and cost-effective way of verifying users’ identities before they can access websites, applications and services. However, there are some restrictions on its use due to local regulations in some countries as well as limitations on what type of information it can verify beyond just code-based messages.
