### What is SMS identity verification?

SMS identity verification is a process that uses text messages to confirm the identity of a user. This method typically involves sending a unique code to a user's mobile phone number, which they must then enter into a website or application to prove that they are the rightful owner of that number. .

### How does SMS identity verification work?

When a user attempts to verify their identity using SMS, the service will generate a one-time code and send it to the user's mobile phone number via text message. The user then enters this code into the website or application to complete the verification process. This helps to ensure that the person attempting to access the account is the legitimate owner of the phone number associated with that account.

### What are the benefits of SMS identity verification?

- **Cost-effective**: SMS verification is a cost-effective method of verifying a user's identity, as it does not require any specialized hardware or software.

### Are there any limitations to SMS identity verification?

- **Reliance on mobile phone service**: SMS identity verification relies on the user having access to a mobile phone with service and signal, which may not always be available.

- **Potential for interception**: While rare, there is a slight risk that SMS codes could be intercepted by malicious actors, compromising the security of the verification process.

Overall, SMS identity verification is a simple and effective method of confirming a user's identity, offering a balance of convenience and security for online accounts and transactions.
