Kali Linux is a distribution based on Debian. It contains a very large collection safety tools and penetration tests.
The project has just released a new version for the year 2020 and it brings a number of important changes. The new version, 2020.1, of Kali Linux merges the various desktop editions into a single option λήψηand removes the ability to run things as root by default.
"Καθ 'όλη τη duration of Kali's history (and its predecessors BackTrack, WHAX and Whoppix), the default credentials were root/toor. This is no longer the case. We no longer use the superuser account, root, as the default in Kali 2020.1. The default account χρήστη είναι πλέον ένας τυποποιημένος χρήστης που δεν έχει προνόμια."
To read the reasons behind this move you can visit a previous post at blog of distribution.
This is a very big change, and the developers are asking you to report any problems.
