Abstract: Embodiments of the present invention provide a security indication information configuration method and device, to reduce a risk of attack and interception from malicious software. The method includes: detecting, by a terminal, whether universal security indication information is set in the terminal for a TUI; detecting a running status of the terminal if no universal security indication information is set; when it is detected that the running status of the terminal is a secure state, presenting a first input interface on a display by using a first information presentation interface; and receiving input universal security indication information by using the first input interface, and saving the universal security indication information to a trusted execution environment TEE of the terminal.
