F5 BIG-IP Application Delivery Controller (TMOS) — Default Password

Default username and password for the F5 BIG-IP Application Delivery Controller (TMOS): admin / admin. Learn how to log in at 192.168.1.245 and how to change the default credentials.

F5 BIG-IP ships with two default accounts: admin / admin for the TMUI web interface and iControl REST API, and root / default for SSH and serial console access. The management interface defaults to 192.168.1.245/24. Both accounts must be secured before network connection. CVE-2020-5902 (BIG-IP TMUI RCE) targeted exposed management interfaces, making default credential hygiene critical.
