* Default "pi" user has been removed; the first-boot wizard enforces the creation of a new user account

Solución: https://www.raspberrypi.com/news/raspberry-pi-bullseye-update-april-2022/

Se crea el fichero: boot/userconf o boot/userconf.txt con el contenido:

username:encrypted-password

La contraseña se encripta:

echo 'mypassword' | openssl passwd -6 -stdin
