For large deployments, create a spreadsheet mapping each device's serial number to its unique default password. Store this in an encrypted vault.
The ZMM220 platform typically runs a Linux-based environment (often Kernel 3.0.8 on MIPS architecture). Multiple sources indicate that the following combinations are the most common default credentials for accessing the device via Telnet (Port 23): root | Password: (blank/empty) Username: root | Password: solokey Username: root | Password: colorkey Username: root | Password: swsbzkgn Username: admin | Password: admin zmm220 default telnet password updated

Mirai malware famously scanned the internet for devices with default Telnet passwords (e.g., root / xc3511 , admin / admin ). It enslaved hundreds of thousands of cameras and routers into DDoS armies. In response, manufacturers like the one producing the ZMM220 began forcing password changes on first boot or disabling Telnet entirely by default. In response, manufacturers like the one producing the
