How is an authentication verification code sent to a user's mobile phone for password reset?

An authentication verification code is typically sent to a user's mobile phone through a voice call message because this method ensures that the user receives the code in a direct and personal manner. Voice calls can be particularly useful for users who may not have reliable access to text messages or who may prefer to hear the code rather than read it. In the context of a password reset, it adds an additional layer of security and user accessibility.

Using voice calls can also enhance the user experience by providing an immediate way to receive the verification code without needing to input any additional information. It allows the user to authenticate themselves verbally, making it a very secure and user-friendly option for critical actions like resetting a password.
