Default Raspberry Pi OS Password

For older Raspberry Pi OS versions, the default login was username pi  and password raspberry . However, since 2022, newer releases (Bullseye/Bookworm+) require you to set a custom username and password during the initial setup via Raspberry Pi Imager or the first boot wizard.

In other words:

• If you're using a fresh install of a recent OS and didn't set one, you're prompted to create one.
• For older systems, use pi /raspberry  and change it immediately.
