Raspberry Pi just made two huge changes for security and convenience India News, The Indian Express
A new update for Raspberry Pi OS (formerly Raspbian) offers several improvements over previous releases, although one of these “improvements” may be a bit controversial. On the one hand, the installation is more convenient and the Pi is more secure. But it’s time to say goodbye to the default user.
As of now, Raspberry Pi OS no longer comes with a default user named “pi”. In addition, the operating system does not give you the default “raspberry” password. That means the Raspberry Pi setup wizard can’t be skipped now, as you’ll need to enter custom credentials. (That said, the default user won’t disappear when you update your Pi, and the new setup wizard won’t stop you from using the “pi” username or the “raspberry” password.)
This change is probably too late. Default usernames and passwords pose a security risk to remote access devices, and of course the Pi is a popular home server solution. (You can run the sudo rename-user command to change the default credentials on an older Pi.)
This latest release removes the default “pi” user and instead creates a user when you first boot a newly flashed Raspberry Pi OS image. This is consistent with the way most operating systems work today, and while it can cause a few issues where software (and documentation) assumes the existence of the “pi” user, it feels like a sensible change to to make this point.
Okay, so you can’t skip the Pi OS setup wizard anymore. But there’s a neat concession here: you can now use Bluetooth keyboards and mice while setting up your Pi. Previously, you had to search for a wired keyboard to even connect a Bluetooth device to the Pi.
Pairing Bluetooth devices while setting up Pi should be fairly easy. You simply put the keyboard or mouse into pairing mode and wait for your Pi to finish the job. The Pi Foundation notes that this works with older Pi models, as long as you have a Bluetooth adapter†
And strangely enough, the new Pi OS update allows you to test the unfinished wayland window system. Wayland is a faster and more secure replacement for X Windows System, which has been the crux of Unix desktop environments for decades. While I recommend not testing Wayland (it’s very buggy), you can do this by running udo raspi-config, going to Advanced options, enabling Wayland and rebooting. (To check if you’re already using Wayland, run echo $XDG_SESSION_TYPE in the terminal.)
The Raspberry Pi OS update is available on the Pi website† To update an existing image, open the terminal, run sudo apt update and run sudo apt full-upgrade. If you want to install Wayland support, you’ll also need to run sudo apt install rpi-wayland – again, I recommend avoiding Wayland for now.
