Change Administrator Password on 2811 Router

We have fired the company who supported our 2811 routers and I would like to know how to change the Administrator password so we can prevent their access while we are looking for a replacement company

You can reduce your risk by creating another account before deleting the admin account.

username administrator secret MyPaSsWoRd

Then create another telnet session (leave the original one open) and authenticate with the username administrator. If successful you can delete admin and re-create or just use the administrator account.

Make sure the new one is working fine before you delete the old one.

the command to delete the old one is:

no username admin

I currently access the 2811 using a telnet connection and CLI commands and login as Admin which has all rights and then the system uses the same password for login and enable functions.

Re: Change Administrator Password on 2811 Router

Thanks but I am not sure I understand, there is a current username admin that I use to login to the router. You are suggesting creating a new one. Is that to overwrite/replace the current user? Maybe I should wait until I find a new company and run the risk.

Re: Change Administrator Password on 2811 Router

First you delete the username admin. Next your creating a new admin account so you can login with that account and the new password.
