Guidelines and Limitations for User Accounts for Devices

Usernames

• You cannot add the same username for both internal and external users. If the external server uses a duplicate username, the deployment to the device fails.

• The username must be Linux-valid:

  • Maximum 32 alphanumeric characters, plus hyphen (-) and underscore (_)

  • All lowercase

  • Cannot start with hyphen (-); cannot be all numbers; cannot include a period (.), at sign (@), or slash (/)

Defaults

All devices include an admin user as a local user account; you cannot delete the admin user. The default initial password is Admin123; the system forces you to change this during the initialization process. See the getting started guide for your model for more information about system initialization.

Number of User Accounts

You can create a maximum of 43 user accounts for the Firepower 1000.
