Go to the glory of the king's homepage and click on the small sign in the upper right corner to enter. On the settings page, we drag down to find the secondary password column to be entered. Under normal circumstances, the secondary password is closed, so we click the secondary password setting on the right to open it.

We need to set our secondary password and we need to confirm it. After successfully setting the secondary password, the word "Open" will be displayed. In the future, when we destroy our own inscriptions, the system will prompt for the secondary password, which will be relatively safe.
