Enable password vs Enable Secret

enable secret password provides encryption automatically using MD5 hash algorithm. The enable password password does not encrypt the password and can be view in clear text in the running-config. In order to encrypt the enable password password , use the service password-encryption command. To be clear, the enable secret password command provides stronger encryption than the service password-encryption command.
