Abstract: Embodiments of the present invention provide a hotspot scanning method and an electronic device. Whether a condition of initiating a hidden hotspot scanning is met is first determined. If the condition of initiating the hidden hotspot scanning is met, a name of a hidden hotspot is obtained. Then, the hidden hotspot scanning is initiated by using the name of the hidden hotspot. If the condition of initiating the hidden hotspot scanning is not met, the hidden hotspot scanning is not initiated. In this way, whether the condition of initiating the hidden hotspot scanning is met is determined before the hidden hotspot scanning is initiated. This effectively reduces a disclosure probability of the name of the hidden hotspot, thereby achieving a purpose of reducing a security risk in hotspot scanning.
