How to create users in CISCO routers

This will allow you to create multiple users on a router and is a handy tool to find out who did what at what time (permitting logging is on and the correct date/time is configured)

We first start of with creating the users using the following command:
username user password password

We use this command for each user we want to create.

Now we enable the use of usernames to login to the router.
We use to following commands:
aaa new-model
aaa authentication login default local

The first line enables aaa or authentication, authorization and accounting. The second line is telling the router to use the local user database which was created in the first step.

Now that this is enabled on the router logging into the router (console, telnet) will prompt for a username/password.
