One vault, connected to your day.

Less friction, more control

From a saved password
to a signed-in tab.

Small, deliberate actions. Your vault stays at the center.

Find what you need

Search and filter your personal vault. Keep logins, cards, identities, and secure notes together, with folders and tags to make them yours.

Fill when you choose

Choose a saved login in Chrome and fill the page. Review a captured login before saving it, and opt into in-page tools when you want them.

Create the next credential

Generate passwords, passphrases, and usernames. Use verification codes and supported passkeys, or connect SimpleLogin or Addy.io for email aliases.

Keep the server.
Choose the client.

P4 Warden connects to the Vaultwarden server you configure. An encrypted local copy helps you access your vault when that server is offline.

Optional desktop pairing brings Mac-assisted unlock to Chrome. Vault timeout settings let you decide how long the client stays unlocked.

Understand how your data is handled

Make it yours

A home for your vault.
A client for your day.

Bring an existing Vaultwarden account and a server reachable over HTTPS with a valid certificate.

Ask about availability
Which Vaultwarden versions are supported?

Vaultwarden 1.37.3 is the verified server version. The client accepts a reported version of 1.37.3 or later with the expected client API configuration, but later versions have not all been verified. P4 Warden is not a general compatibility guarantee for every Bitwarden server.

Do I need a desktop app to use Chrome?

No. You can connect the extension directly to your supported Vaultwarden server. The Mac app is needed for optional desktop-assisted unlock; the Windows app does not offer it. Email aliases separately require a supported provider account.

What should I know about offline access?

Offline access uses the last encrypted vault copy stored on your device. It does not fetch new server changes. Lock and session-retention behavior depend on your settings; read the privacy policy before choosing a persistent session.
