Kali Linux Default Passwords
This page is dated. You can find the latest version here: https://www.kali.org/docs/introduction/default-credentials/.
During installation, Kali Linux allows users to configure a password for the root user. However, should you decide to boot the live image instead, the i386, amd64, VMWare and ARM images are configured with the default root password - "toor", without the quotes.
