How to modify a Carbon Black User without access to the UI

How to modify a Carbon Black User without access to the UI


This solution applies to all Carbon Black versions.


This solution explains how to reset a User's password, unlock a User, and add a new User.  Note that the User refers to a Carbon Black UI User, not an operating system User.


Log on to the Carbon Black server, run the following command(s), then continue by following the prompts.  For example cbpasswd --reset <user> will prompt you to enter and confirm the new password for the <user> User.

Change User's password:

/usr/share/cb/cbpasswd --reset=<user>

Note: Resetting a users password does not automatically unlock the account if it is locked out.

Unlock a User:

/usr/share/cb/cbpasswd --unlock=<user>

Note: You may get the following line when unlocking a users account. This does not mean it did not unlock it but rather displays a warning.

[root@cbresponse ~]# /usr/share/cb/cbpasswd --unlock=test

Two Factor Auth not configured.

Add a User:

/usr/share/cb/cbpasswd --add=<user>

If you are unaware of the username that was initially configured, one may run the following command on the system as the root user to query the cb_user table to see the list of usernames:

psql -d cb -p 5002 -c "select username from cb_user;"
