Background technique

With the rapid development of science and technology, electronic devices (mobile phones, tablet computers, etc.) have already possessed powerful processing capabilities, and have changed from simple tools to a comprehensive information processing platform. Most users save their personal privacy in electronic devices. In order to protect personal privacy in electronic devices, various unlocking passwords are usually set to ensure the security of personal privacy; for example, when an electronic device is turned on, a power-on password is set; when an electronic device is used, a screen unlock password is set ; When using various APPs (Alipay, Notepad, Contacts) on the electronic device, a management password will also be set.

Although the more unlocking passwords are set in the electronic device, the higher the security of personal privacy in the electronic device is. However, as the number of unlocking passwords increases, and according to the usage of each unlocking password, the possibility of forgetting part of the unlocking passwords will correspondingly increase, thereby bringing great inconvenience to the user. At present, there are also unlocking methods for forgetting the unlocking password. For example, when the user forgets the power-on password, obtain root authority, then press and hold the volume button and power button, clear the cache and all data, and restore the factory settings.

However, this unlocking method will not only clear the cache and all data, thereby causing great inconvenience to the user; it is also only suitable for removing the power-on password, especially not suitable for removing various APPs (Alipay, Notepad, etc.) on the electronic device.
