Kali Linux is a distribution based on Debian. It contains a very large collection of security tools and penetration tests.
The project 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 download option and removes the ability to run various as root from beforechoice.
"Καθ 'όλη τη διάρκεια της ιστορίας του Kali (και των προκατόχων του BackTrack, WHAX και Whoppix), τα προεπιλεγμένα διαπιστευτήρια ήταν root/toor. Αυτό δεν ισχύει πια.Δεν χρησιμοποιούμε πλέον τον account superuser, root, σαν προεπιλογή στο Kali 2020.1. Ο προεπιλεγμένος λογαριασμός χρήστη είναι πλέον ένας τυποποιημένος χρήστης που δεν έχει προνόμια."

This is a very big change, and the developers are asking you to report any problems.
