Note, on Linux when entering a password it will not be displayed on the screen for you to see (for security reasons) so it’s best to type it out in a text file and then Copy and right-click on the cmd interface, SSH to paste the password. This will reduce errors when typing the password directly.

In the Retype new password: You continue to re-enter the password or continue to -click to paste the password to confirm. The following image will illustrate the above operations.

You enter your password in New password and continue re-entering your password in Retype new password and you’re done.
