Re: Remove Password encryption

Once encrypted passwords will stay so until you cancel encryption with no keyword AND enter them from command line again.

Collin has given exactly the right answer. But it may not seem that way when you apply the no service password-encryption command. Be aware that this command turns off password encryption. But that passwords that have been encrypted and stored in the config as encrypted will remain encrypted even when you turn off the service. The only way to get those passwords into clear text is to configure the passwords again after the service for encryption is turned off.

Andriy is correct. Since these are VTY passwords they must be removed then re-added. You could also reverse the password since these passwords have weak encryptions.

no service password-encryption

With most Cisco configurations, the no keyword removes the command.
