Hello Friend.
To change the username and password on a standby firewall, follow these steps. These instructions are generic, but I can tailor them more specifically based on the firewall model if you need.

Steps to Change Username and Password on Standby Firewall
Log into the Active Firewall:
Access the active firewall first, as configurations are often synchronized between active and standby devices.

Disable Configuration Synchronization Temporarily:
On some firewalls, you might need to disable synchronization to avoid automatic overwriting of credentials on the standby device. This depends on the firewall type (e.g., on Cisco ASA, this is known as "Failover" configuration sync).

Access Standby Firewall Directly:
Use direct access to the standby firewall through console access or SSH (if it has a unique IP address for standby). You should be able to log in using the current credentials.

Change Username and Password:

Use the firewall's command-line interface (CLI) to change credentials.
For Cisco ASA, for example, you’d enter:
plaintext
Copy code
username <new-username> password <new-password> privilege <level>
On other firewalls, this could vary, so refer to the documentation for precise syntax.
Re-enable Configuration Synchronization:
Once the credentials are updated on the standby firewall, re-enable synchronization so that other settings can sync between the active and standby firewalls.

Verify Configuration Sync:
Ensure that the active firewall detects the standby firewall properly and that both units are synchronized. Most firewall interfaces have a "Failover" or "HA" status section to confirm this.

Test Access with New Credentials:
Log out and test the new credentials to verify that they are working as expected.
