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