| Generation | Recovery Method | |------------|----------------| | iLO 2 / 3 | Use BIOS RBSU to reset iLO to factory defaults (password becomes blank). Requires physical access. | | iLO 4 | Use → iLO 4 Configuration → Reset iLO to factory defaults. Password reverts to the unique tag value (still unknown if tag lost). Then use iLO Dedicated Network Port and password recovery service via HPE. | | iLO 5 / 6 | Use iLO Configuration Utility from host OS (if installed) or physical BIOS to reset iLO. If the unique password is lost, HPE support can generate a one-time override using the serial number and a secure token. | 7. Conclusion The default iLO password for iLO 2 and 3 is often blank or a common weak value like Admin . For iLO 4, 5, and 6 , there is no single default password; each unit ships with a unique credential printed on the chassis. Security best practices demand that these unique credentials be rotated immediately upon deployment. Leaving any default iLO credential – even a unique one – unchanged represents a critical risk.
