Connect your Bitwarden clients to your Vaultwarden server

Your Vaultwarden vault is ready on Bunker. Now you need to configure your devices to connect to it. This tutorial covers the browser extension, desktop app, and mobile app.

Prerequisites​

  • An active Vaultwarden account on Bunker (contact [email protected] to get one)
  • Having accepted the invitation received by email and created your master password
  • Knowing your server URL (default: https://vault.getbunker.net, or the custom domain provided by Bunker)

To learn more about Vaultwarden and its advantages, see the Password Manager guide.

Browser extension​

The Bitwarden extension is available for Chrome, Firefox, Edge, and Safari.

Installation and configuration​

  1. Install the extension from your browser's store
  2. Open the extension. The login screen appears
  3. Click the "Logging in on" dropdown
  4. Select "Self-hosted"
  5. In the "Server URL" field, enter your vault address: 
    https://vault.getbunker.net
  6. Click "Save"
  7. Log in with your email address and master password
One URL is enough

Vaultwarden exposes all its services under a single domain. No need to fill in the "Custom Environment" section — the Server URL field is all you need.

Enable autofill​

Once logged in:

  1. Click the extension icon in your browser toolbar
  2. Go to Settings (gear icon)
  3. Under Auto-fill: enable "Offer to save and fill passwords"
  4. Optional: enable "Auto-fill on page load" (disabled by default for security reasons)

The default keyboard shortcut to fill a form is Ctrl+Shift+L (or Cmd+Shift+L on macOS).

Desktop app​

The desktop app is available for Windows, macOS, and Linux at bitwarden.com/download.

Configuration​

  1. Launch the application
  2. On the login screen, click the "Logging in on" dropdown
  3. Select "Self-hosted"
  4. Enter the server URL: 
    https://vault.getbunker.net
  5. Click "Save"
  6. Log in with your credentials

The desktop app supports multiple accounts on different servers. Each account keeps its own configuration.

Mobile app​

The Bitwarden app is available on iOS (App Store) and Android (Google Play).

Configuration​

  1. Install the app from your store
  2. Open it. The login screen appears
  3. Tap the "Logging in on" dropdown
  4. Select "Self-hosted"
  5. Enter the server URL: 
    https://vault.getbunker.net
  6. Tap "Save"
  7. Log in with your credentials
Biometric unlock

On mobile, enable fingerprint or Face ID unlock in Settings > Security for quick access without re-entering your master password.

Custom domain​

If your organization has a dedicated domain (e.g. vault.mycompany.com), use that URL instead of vault.getbunker.net in all the steps above. The exact URL is provided by Bunker during setup.

Organizations: sharing passwords across your team​

Vaultwarden lets you share credentials between team members through organizations. This is useful for internal tools, service accounts, or any shared credentials.

Joining an organization​

  1. Your administrator sends you an invitation from the Vaultwarden web interface
  2. You receive an invitation email
  3. Accept the invitation by clicking the link
  4. The organization appears in the sidebar of your Bitwarden clients

Accessing shared credentials​

Organization credentials are accessible from all your clients (extension, desktop, mobile). They appear in a separate section, distinct from your personal vault.

Personal vault vs organization

Items in your personal vault are visible only to you. Organization items are accessible to all members (based on permissions set by the administrator).

Troubleshooting​

"Cannot connect to server"​

  • Check that the URL starts with https:// (not http://)
  • Check there is no trailing slash (/) at the end of the URL
  • Test the URL in your browser: you should see the Vaultwarden login page
  • If you are on a corporate network, check that a proxy or firewall is not blocking access

"Invalid credentials"​

  • Your account is tied to the server where it was created. If you previously used bitwarden.com, your credentials will not work on the Bunker server (and vice versa)
  • Make sure you accepted the invitation email before attempting to log in

The extension does not offer to fill a form​

  • Check that autofill is enabled in the extension settings
  • Some websites use non-standard form fields that Bitwarden cannot detect. Use the Ctrl+Shift+L shortcut to force fill
  • Check that the saved login matches the URL of the site you are visiting

The vault does not sync between devices​

  • Bitwarden syncs automatically every 30 minutes
  • To force a sync: Settings > Sync > Sync vault now
  • Check that all your devices point to the same server URL

Invalid SSL certificate​

  • The Bitwarden extension rejects self-signed certificates. Bunker uses valid Let's Encrypt certificates — this issue should not occur. If it does, contact [email protected]
Updates

Vaultwarden server updates are transparent and backward-compatible. In the rare case where a Bitwarden client update would be required, you will be notified by email in advance.

Vault lock settings​

The lock timeout is configurable in each client individually:

  1. Go to Settings > Security
  2. "Vault timeout": choose the idle duration before locking (1 minute, 5 minutes, 1 hour, etc.)
  3. "Vault timeout action": choose between lock (requires master password or biometrics) or log out

For a shared workstation, a 1-minute lock timeout is recommended.
