1. Use an alternate PIN: If an alternate PIN is set in the system settings, you can try to log in with an alternate PIN. The spare PIN code is a spare password set to prevent forgetting the original PIN code when setting the PIN code.
2. Use account password: If your system supports login with account password, you only need to choose to log in with account password when logging in, and then set a new PIN code.
3. Reset PIN code: If the above two methods are not feasible, try to reset PIN code. In Windows system, you can choose "Forgot PIN" at the bottom of the login page, and then follow the system prompts to reset the PIN.
It should be noted that resetting the PIN code will lead to your data, account, etc. There must be some risks, so please be careful. Before resetting the PIN code, it is recommended to back up data and close the storage of confidential information. At the same time, if you are a member of an enterprise or organization, it is recommended to seek help or consultation from the administrator or technical support personnel.
