Single user mode (rescue mode) is used for recovery when the system detects an issue during boot or by manual selection from the bootloader.

Requiring authentication in single user mode (rescue mode) prevents an unauthorized user from rebooting the system into single user to gain root privileges without credentials.
Fix:
Run the following command and follow the prompts to set a password for the root user: passwd root
Parameter:
[yes/no]
Technical Mechanism:
Run the following command and follow the prompts to set a password for the root user: passwd root
