Hi Hussein,

Now I understand your question :slight_smile:

There are two methods:

  1. username hussein password cisco123

If you do it like this, then it will be saved in the configuration in clear text.

  1. username hussein secret cisco123

If you use “secret” then it will create a MD5 hash of your password.

You can’t have a “password” and “secret” at the same time for one user account so you are getting this error because you probably already configured a secret for your username. Remove it first and then you can set a password.

It’s also possible to encrypt all plaintext passwords in the configuration with the “service password-encryption” command. However, this is a very poor encryption type:
