# Headless Raspberry Pi setup: there is no default 'pi' user anymore

> Since the April 2022 Raspberry Pi OS release there is no default pi user. For headless IoT devices, preconfigure user, Wi-Fi and SSH in Raspberry Pi Imager's customisation, or use userconf.txt and the ssh file on the boot partition.

## Symptom

Old tutorials say "log in with `pi` / `raspberry`". On a freshly flashed Raspberry Pi OS image that fails, and a headless Pi without a screen seems unreachable.

## Why

With the **April 2022** Raspberry Pi OS (Bullseye) release, the default `pi` user was removed. A user is now created at **first boot** (desktop wizard, or text prompts on Lite), or **preconfigured** before the first boot. Existing installations kept their `pi` account.

## Option 1: Raspberry Pi Imager (recommended)

In Imager, after choosing device and OS, use the **Customisation** tab:

1. **Hostname**: unique per device (e.g. `gw-kitchen-01`).
2. **Localisation**: this also sets the Wi-Fi regulatory domain.
3. **User**: username and password (lowercase letters, digits, `_`, `-`).
4. **Wi-Fi**: SSID and password. For a headless device this is essential, because it must be online at first boot. Enable *Hidden SSID* if the network doesn't broadcast.
5. **Remote access**: enable **SSH**, preferably with public-key authentication instead of a password.

Then write the card and boot. Find the device by hostname (`ssh user@gw-kitchen-01.local`) or in the router's DHCP list.

## Option 2: files on the boot partition

For scripted provisioning of many cards:

```bash
# on the boot partition of the freshly written card
touch ssh                                   # enable SSH at next boot
echo "admin:$(openssl passwd -6)" > userconf.txt   # username:encrypted-password
```

The April 2022 announcement describes `userconf` / `userconf.txt` with a single `username:encrypted-password` line. Wi-Fi also needs configuring; Imager's customisation is simpler and handles current OS versions.

## Hardening for IoT gateways

- Use SSH keys and disable password login once keys work.
- One user per purpose: run services as a dedicated, non-sudo user (add it to `gpio`, `i2c`, `dialout` groups only as needed).
- Give every device its own hostname and credentials; never clone one password across a fleet.

## Claims

- Raspberry Pi Imager's OS customisation can preconfigure the username and password, Wi-Fi credentials and SSH before the image is written. (unverified)
- Since the April 2022 Raspberry Pi OS Bullseye release, newly flashed images have no default 'pi' user; a user is created on first boot or preconfigured. (unverified)
- Creating an empty file named ssh in /boot/firmware enables SSH on the next boot. (unverified)
- A user can be preconfigured headlessly with a userconf or userconf.txt file in the boot partition containing username:encrypted-password. (unverified)
