Frequently Asked Questions

What is Silent Number Verification

open vertical icon

Number Verify, also known as Silent Number Verification, is a verification method that leverages the SIM card to verify a user. It's a background process that validates phone numbers via mobile operator data - the user only has to enter a phone number. It's considered a faster and more secure verification procedure than traditional authentication methods.

What Is a One Time Password?

open vertical icon

A One Time Password or OTP is a security code designed to be used for a single login attempt, to minimize the risk of fraudulent login attempts and maintain high security. It’s a string of characters or numbers automatically generated and sent to the user’s phone via SMS, Voice, or Push message.

The OTP has become the standard method worldwide of enabling a login when special circumstances apply, such as validating a new account or confirming a transaction is legitimate.

open vertical icon

SIM Swap Fraud, also known as SIM Swap Scam, is a type of identity theft that occurs when a fraudster gains control over a victim’s mobile phone number by persuading a mobile carrier to transfer the number to a SIM card in the scammer’s possession. Once the fraudster has control of the phone number, they can access sensitive information, such as text messages, phone calls, and, often, accounts that use SMS One Time Passwords (OTPs) for two-factor authentication (2FA).
