forget router user and password

[Qamrul huda]

Dear All,

I forget my CISCO1921-SEC/K9 and cisco 1941 routers user and password. So I want to reset my router. I have tried by following method, but did not success. Every time ask user name and password for User Access Verification. Pls. help me.  

Method1:

I am tried to factory reset by press reset button. Did not work

Method2:

1) Connect via console to the device

2) Power on the device

3) Hit ctrl+break until you are in rommon mode

Type confreg 0x2142 at the rommon 1> prompt in order to boot from Flash.

This step bypasses the startup configuration where the passwords are stored.

Type reset at the rommon 2> prompt.

The router reboots, but ignores the saved configuration.

Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.

Type enable at the Router> prompt.

You are in enable mode and should see the Router# prompt.

Thanks,

Qamrul

i tried but failed. now i need to try by following method. but i don't know how can i remove flash from router and what is step?

If unable to break into ROMMON mode, perform these steps:

1. Remove flash.

2. Reload the router. Router will end up in ROMMON mode.

3. Insert flash.

4. Perform standard procedure for password recovery.

I believe the flash in a 1900 router is stored on a CF card and needs to be removed physically.

See this guide:

http://www.cisco.com/c/en/us/td/docs/routers/access/1900/hardware/installation/guide/19cf.pdf

If you follow the password reset procedures exactly and ensure you use the correct break sequence key, it will work as I have done it myself several times on both models of router.

FYI - Your screenshots include some client information so I would remove this. 

Thanks
