Resetting your Console Password
In certain rare cases, it can be necessary to reset the console password for the admin account. If you have become locked out of your shell, you can use the following steps to reset the password.
- First, reboot your system, then select the kernel you want to boot into and press the 'e' key to interrupt the boot-process as shown in Screenshot 01.

- Now we must remount the filesystem into read/write mode. Use the following command, as shown in Screenshot 03.
mount -o remount,rw /sysroot

- Finally, we can change the password for the root user with the 'passwd' command.

- The password is changed, but before rebooting it is important to create a file with the following command, as shown in Screenshot 06.
touch ./autorelabel
- Type 'exit' to exit out of chroot jail and then 'exit' again to logout and reboot your system.
