Which of the following is NOT a valid way to recover your password?

The correct answer highlights that using a temporary password sent via SMS is not typically recognized as a valid recovery method for passwords. While SMS can be used for two-factor authentication or as a method for receiving codes, the prevailing protocols for password recovery often involve more secure and reliable means, such as authentication questions or email resets.

Using an authentication question provides a direct method for confirming identity based on information that should only be known to the user. Resetting through email is a common practice, ensuring that the user has access to the email account associated with their account, thus validating their identity. Requesting a new password from technical support is also acceptable, as support teams can verify the user's identity through various means before issuing a new password.

In contrast, messages sent via SMS may not always guarantee secure transmission, as they can be intercepted more easily than email or secured authentication processes. Hence, this method lacks the necessary reliability and integrity expected in official password recovery protocols, leading to the conclusion that it is not a valid way to recover a password.
