1. Contact Your System Administrator
If you are part of a company or organization, contact your system administrator to reset your password. They will perform appropriate authentication checks before resetting the password.
2. Use a Password Reset Disk
If you created a password reset disk in the past, you can use it to reset the password. However, this method only works if you had the disk before forgetting the password.
