Install Docker

Before we start, please ensure you have Docker installed. This can be installed through the Synology Package Center.

Create the Docker Folder

Head into File Station and open the Docker folder. Select Create, choose Create folder and name it vaultwarden. (see demonstration)

Create Reverse Proxy

Admin Settings

Head over to to get started.

You will see the following screen. Enter you admin token. This is the token you added to the Docker run/Compose code. Press Enter.

If you noticed in the Docker code, we disabled signups so we need to invite ourself as a user to our Vaultwarden.

Under Settings, click General settings. Under Domain URL, enter the URL to your Vaultwarden. This is all we’ll change here. Feel free to scroll down and change any settings accordingly. Scroll to the very bottom and press Save.

Head into SMTP Email Settings. If you are lucky enough and Self-hosting your email, feel free to go ahead and input your SMTP Settings. For me I’ll be using Office365 SMTP Settings. Go ahead and fill out the SMTP details. Press Save.

Ensure you fill out the SMTP details correctly otherwise you won’t be able to continue.

Once saved, go back into SMTP Email Settings, scroll down until you see Test SMTP. Enter your email address and press Send test email. If you receive an error at this point, double check your details. Once you receive the test email, continue.

From the top menu, select Users. Down at the bottom under Invite User, enter your email address and press Invite.

Check your email, click the Join Organization button. On the page that loads, click Create account. Now fill in your details and press Create acount.

That’s you all done, you can now log in and enjoy Vaultwarden.

Linking your app to your Vaultwarden is very simple. On your mobile, load up your app store and search for Bitwarden Password Manager. Open the app and click the little settings icon at the top right. Under Self-hosted environment, enter the link to your Vaultwarden i.e Press Save. Simply login and you are good to go. Use this same process for Browser extensions you wish to use
