Vaultwarden: The Armory of Secrets
The Instructor's Perspective
In the Army, “security of information” was paramount. In your lab, your passwords are your most vulnerable asset. Using a password manager isn’t just a suggestion; it’s a requirement for a professional environment. Vaultwarden gives you all the power of Bitwarden, but on your own hardware, under your own control.
Why use it?
- Self-Hosted Security: You own the data and the encryption keys.
- Cross-Platform: Access your secrets from your phone, browser, and desktop.
- Organization: Share passwords securely with family, students, or peers.
- Zero-Knowledge: Your data is encrypted before it ever leaves your device.
Secrets Reliability (The PACE Plan)
Information Discipline
P (Primary): Local Vaultwarden instance (Docker/LXC on Proxmox). A (Alternate): Encrypted local backup of the Vaultwarden database (
db.sqlite3). C (Contingency): Bitwarden (Cloud-hosted) with a subset of critical recovery keys. E (Emergency): Printed “Emergency Kit” with master password and 2FA recovery codes in a fire-safe.
SOP: Managing Secrets
- Generate Passwords: Always use the built-in generator. 20+ characters, mixed symbols.
- Use 2FA: Enable Multi-Factor Authentication for both Vaultwarden and all the accounts it manages.
- Regular Backups: Ensure your database and attachments are part of your daily backup routine.
- Audit Your Vault: Periodically check for weak or reused passwords using the “Reports” feature.
