Vaultwarden is an unofficial Bitwarden server implementation written in Rust. Vaultwarden is compatible with the official Bitwarden clients, and is ideal for self-hosted deployments where running the official resource-heavy service is undesirable. In this step by step guide I will show you how to install Vaultwarden on your Synology NAS using Docker. If you are a more proficient user, I recommend the following installation for Vaultwarden: Install Vaultwarden With Portainer. Note: If you want to Install the official Bitwarden, check out my new article on How to Install Bitwarden on Your Synology NAS.

💡Note: This guide works perfectly with the latest version of Vaultwarden 1.33.2

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

Install Container Manager via Synology “Package Center”. If you run an older DSM version (under 7.2), search for Docker instead of Container Manager.

• STEP 3

Make sure you have a synology.me Wildcard Certificate. Follow my guide to get a Wildcard Certificate. If you already have a synology.me Wildcard certificate, skip this STEP.

• STEP 4

Go to Control Panel / Login Portal / Advanced Tab / click Reverse Proxy. Follow the instructions in the image below.

Now click the “Create” button. Follow the instructions in the image below.

After you click the Create button, the window below will open. Follow the instructions in the image below.

On the General area, set the Reverse Proxy Name description: type in Vaultwarden. After that, add the following instructions:

Source:
Protocol: HTTPS
Hostname: vaultwarden.yourname.synology.me
Port: 443

Check Enable HSTS

Destination:
Protocol: HTTP
Hostname: localhost
Port: 5151

• STEP 7

On the Reverse Proxy Rules click the Custom Header tab. Click Create and then, from the drop-down menu, click WebSocket. After you click on WebSocket, two Header Names and two Values will be automatically added. Click Save. Follow the instructions in the image below.

Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 11

Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the image below.

--restart always \
vaultwarden/server

Note: Before you paste the code above in the Run command area below, change the value for the ADMIN_TOKEN with your own value. mariushosting007mariushosting@@@ is an example for an admin token, you should invent your own admin token. Note: A long admin token is better. You can use letters, numbers and special characters.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
