Step 1:
-
Type the below commands
enable, enter
Configure terminal, enter
enable Password (Password is cisco) enter,
Logout, enter.
Remember to save your configurations either by typing the command do wr or by typing copy running-config startup-config at the privilege exec level - This is in plain text and is not very secure (It can be seen by running the Show running-config cmd)
- Logout

Step 2:
-
Type as below
Enable, enter
Password: Cisco, enter

Step 3:
- Cisco's resolution to the problem of plain text passwords was to use one-way md5 authentication
- Enable secret takes precedence over plain text passwords so you can have both, however one will overide the other
-
Type the Below::
enable, enter
configure terminal, enter
enable secret cisco, enter

Step 4:
- Let's test to see if this is encrypted
- By Running the Show running-config command we can see it's encrypted
-
Type the below:
enable, enter
show running-config, enter
