What Is a Raspberry Pi 5 Self-Hosted Bitwarden Server? 🧠

A Raspberry Pi 5 self-hosted Bitwarden server setup lets you run Bitwarden RS (the official Rust server) on your own hardware. It’s an open-source password manager—browser extensions, mobile apps, desktop clients—all sync to your Pi 5 instead of a shared cloud.  

Total data ownership. Zero subscription fees. Encrypted vaults travel only over your network.  

---

Why Choose Self-Hosted Bitwarden on Pi 5?

Because password leaks still happen. Big name breaches in 2025 exposed millions of credentials.  

- Privacy: your vault lives in your home/office.  

- Cost: Pi 5 + SSD < \$100 one-time, versus \$36/year cloud plan.  

- Performance: Pi 5’s A76 cores handle hundreds of users.  

- Flexibility: customize backups, retention, plugins.  

Real talk: I lost access to my cloud vault after a service outage in 2024—accounts locked out, hours wasted. Since self-hosting on my Pi 5, I never worry about vendor downtime.

Step-by-Step Guide: Raspberry Pi 5 Self-Hosted Bitwarden Server Setup

> Pro tip: follow each step, test immediately—if something breaks, you’ll know where.

3.1) Flash Raspberry Pi OS Lite & Enable SSH

1. Download Raspberry Pi OS Lite (64-bit) from raspberrypi.com.  

2. Use BalenaEtcher or Raspberry Pi Imager to flash a 16 GB+ microSD.  

3. After flashing, mount the boot partition on your PC.  

4. Create an empty file named ssh (no extension) in that partition.  

5. Eject, insert into Pi 5, connect Ethernet, power it on.  

Sometimes I forget the ssh file—then I end up plugging in a monitor and keyboard. Avoid that—add ssh first.

---

3.2) Assign Static IP & Update OS

SSH in from your laptop:

`bash

ssh pi@192.168.1.100

`

Change the default password:

`bash

passwd

`

Edit network config:

`bash

sudo nano /etc/dhcpcd.conf

`

Add at the end:

`

interface eth0

static ip_address=192.168.1.100/24

static routers=192.168.1.1

static domainnameservers=1.1.1.1 8.8.8.8

`

Save (Ctrl+O, Enter), exit (Ctrl+X), then:

`bash

sudo reboot

`

Once back, run:

`bash

sudo apt update && sudo apt upgrade -y

`

Static IP prevents your raspberry pi 5 self-hosted bitwarden server setup from vanishing mid-sync.

---

3.3) Install Docker & Docker Compose

Rather than manual installs, leverage Docker for isolation:

`bash

curl -fsSL https://get.docker.com | sh

`

Add the pi user to Docker group:

`bash

sudo usermod -aG docker pi

`

Log out and back in, or reboot. Then install Docker Compose:

`bash

sudo apt install -y docker-compose

`

Quick test:

`bash

docker run hello-world

`

If you see Hello from Docker!, you’re set.

---

3.4) Create docker-compose.yml for Bitwarden RS

Make a project directory:

`bash

mkdir ~/bitwarden && cd ~/bitwarden

`

Create docker-compose.yml:

`yaml

version: "3.8"

services:

  api:

    image: bitwardenrs/server:latest

    container_name: bitwarden

    restart: unless-stopped

    environment:

      - DOMAIN=https://vault.example.com

      - ADMIN_TOKEN=ChangeThisAdminToken

      - SIGNUPS_ALLOWED=false

      - LOG_LEVEL=info

    volumes:

      - bw-data:/data

    ports:

      - 80:80

      - 3012:3012

volumes:

  bw-data:

`

- DOMAIN: your DDNS or domain name.  

- ADMIN_TOKEN: long random string, save it safely.  

- SIGNUPS_ALLOWED=false: lock registrations (optional).  

Save, exit.

---

3.5) Configure Environment Variables

Instead of plain text in yml, you can use a .env file:

Create .env:

`bash

nano .env

`

Add:

`

DOMAIN=https://vault.example.com

ADMIN_TOKEN=ChangeThisAdminToken

SIGNUPS_ALLOWED=false

LOG_LEVEL=info

`

Then in docker-compose.yml, replace env lines with:

`yaml

env_file:

  - .env

`

Mix and match—whichever feels cleaner.  

---

3.6) Launch Bitwarden RS Containers

From ~/bitwarden:

`bash

docker-compose up -d

`

Wait ~30 seconds. Check logs:

`bash

docker logs -f bitwarden

`

You should see:

`

[INFO] Rocket has launched from http://0.0.0.0:80

`

If you see errors about ADMIN_TOKEN, re-run with a longer token.  

Open your browser to http://192.168.1.100—you’ll hit the Bitwarden RS web vault.  

Pro tip: bookmark http://vault.example.com once DNS propagates.

---

3.7) Obtain SSL Certificates with Let’s Encrypt

For HTTPS, install Certbot:

`bash

sudo apt install -y certbot

`

Stop Bitwarden (so Certbot can bind port 80):

`bash

docker-compose down

`

Request a cert:

`bash

sudo certbot certonly --standalone -d vault.example.com --email you@example.com --agree-tos --non-interactive

`

If successful, certificates live in /etc/letsencrypt/live/vault.example.com/.  

Update docker-compose.yml to mount them:

`yaml

services:

  nginx:

    image: nginx:stable-alpine

    container_name: bitwarden-nginx

    restart: unless-stopped

    ports:

      - 80:80

      - 443:443

    volumes:

      - ./nginx.conf:/etc/nginx/nginx.conf:ro

      - /etc/letsencrypt:/etc/letsencrypt:ro

    depends_on:

      - api

  api:

    ...  # as before

`

Create nginx.conf:

`nginx

events {}

http {

  server {

    listen 80;

    server_name vault.example.com;

    return 301 https://$host$request_uri;

  }

  server {

    listen 443 ssl;

    server_name vault.example.com;

    ssl_certificate /etc/letsencrypt/live/vault.example.com/fullchain.pem;

    sslcertificatekey /etc/letsencrypt/live/vault.example.com/privkey.pem;

    location / {

      proxy_pass http://bitwarden:80;

      proxysetheader Host $host;

      proxysetheader X-Real-IP $remote_addr;

    }

    location /notifications/hub {

      proxy_pass http://bitwarden:3012;

      proxyhttpversion 1.1;

      proxysetheader Upgrade $http_upgrade;

      proxysetheader Connection "upgrade";

    }

  }

}

`

Bring it back:

`bash

docker-compose up -d

`

Visit https://vault.example.com—your vault is now encrypted and secure.

Comparing Cloud Bitwarden vs. Self-Hosted Bitwarden (No Tables)

Cloud Bitwarden  

• Pros: instant signup; managed updates; official support.  

• Cons: subscription fees; shared multi-tenant environment; potential vendor breach.

Self-Hosted Bitwarden on Pi 5  

• Pros: one-time hardware cost; total data ownership; custom backups; private network.  

• Cons: you handle updates; SSL renewals; occasional Docker quirks.

Choose self-hosted if you value control over convenience.

My Password-Loss Nightmare: Bitwarden Saves the Day

In early 2024, I left my laptop on a train—password manager locked behind an MFA key stored on that very laptop. Locked out everywhere.  

After self-hosting Bitwarden RS on Pi 5, I regain any vault via mobile app—MFA codes stored separately. No more single point of failure. Real talk: it’s peace of mind.

---

Frequently Asked Questions (FAQ)

Q1: Can I enable user signups?

A: Set SIGNUPS_ALLOWED=true in .env. Monitor registrations to prevent abuse.

Q2: How do I back up the vault?

A: Simply snapshot the bw-data volume:  

`

docker run --rm -v bitwarden_bw-data:/data -v ~/backups:/backup alpine \

  tar czf /backup/bw-backup-$(date +%F).tar.gz -C /data .

`

Q3: What if my Pi reboots and doesn’t auto-start?

A: Ensure docker-compose is in a service. Add to crontab on reboot:  

`

@reboot cd /home/pi/bitwarden && docker-compose up -d

`

Q4: How many users can Pi 5 handle?

A: With 4 GB RAM and SSD, ~10–20 active users before you need caching or a beefier server.

Q5: Can I integrate with LDAP or SSO?

A: Bitwarden RS supports LDAP via the LDAP_ENABLED and related env vars—check the GitHub README.

Why This Matters in 2026 🌙

As privacy regulations tighten—and more breaches hit headlines—the raspberry pi 5 self-hosted bitwarden server setup keeps your keys under your roof. No shared clouds, no surprise data mining. You call the shots on updates, backups, and security posture.

---

What You Can Take Away 📝

- Always secure your ADMIN_TOKEN and backup .env.  

- Automate Let’s Encrypt renewals:  

  `

  0 3   * certbot renew --quiet && cd ~/bitwarden && docker-compose restart nginx

  `  

- Monitor logs:  

  `

  docker logs -f bitwarden

  `  

- Test backup restores on a spare Pi before trusting them.  

- Consider a UPS for Pi 5—no mid-backup power losses.
