The default 'Pi' user in the Raspberry Pi OS has been removed for security reasons.

 The official Raspberry Pi blog published an article today describing the changes in the most recent version of Raspberry Pi OS Bullseye. The most significant change is in the user account creation procedure, which will no longer include a default username, giving users an added degree of protection by allowing them to establish a personalized username right away.

The Raspberry Pi is recognised for being very simple to set up for newbies, thanks in part to the default username of 'pi.' However, by requiring each new user to use the same username, it was insured that only a tiny percentage of users would use the Pi without changing the value to something unique. Bad actors may find it simpler to get access to Pi hardware if numerous users use a single login. Any would-be hackers are now one step further away thanks to this minor tweak.

This modification also necessitates the implementation of new setup procedures for new operating system installations. Users will now be presented by the setup wizard with a blank box to establish their own username when flashing a microSD card with a new instance of Raspberry Pi OS.
