The default credentials in question are nearly ubiquitous in the IT world: Administrator for the username and the blank or empty string for the password. Some variations of iLO firmware have also used a blank password for the admin account, but the most classic and widely documented default for iLO 4 is the Administrator account with no password. This design choice was originally made for ease of initial configuration. When a technician unboxes a new server, they can connect to iLO over a dedicated network port using a web browser or SSH client, log in without a password, and immediately begin configuring the network settings, setting a proper password, and updating firmware. The key philosophy was that physical access to the server (or a direct crossover cable) would be required before the iLO could be exposed to a wider network, making the blank password a minor risk.
