How to Reset Password Using Single User Mode?

Resetting a password using single user mode can be a helpful solution if you find yourself locked out of your system. Single user mode is a boot mode in Unix-like operating systems that allows you to access the system with superuser privileges.

To reset your password using single user mode, follow these steps:

1. Boot your system into single user mode. This process varies depending on the operating system you are using.
2. Once in single user mode, you will have access to a root shell prompt.
3. Enter the command to remount the file system as read-write to make changes: mount -o remount,rw /
4. Next, enter the command to change the password for a specific user. For example, to change the password for user 'john', you would use: passwd john
5. Follow the instructions to set a new password. Once done, reboot your system.

It's important to note that resetting a password using single user mode requires a good understanding of system processes and can be complex for inexperienced users. Proceed with caution and avoid making any unintended changes.
