Teampass is a self-hosted password manager for teams, built for organizations that can't afford to hand their credentials to a third-party cloud. It's been maintained since 2009, runs on Docker or bare metal, and every security and governance feature ships in the free, GPL-3.0 server.

The access model centers on a folder tree. Roles carry preset rights, per-user overrides are available, and the same rules apply in the web interface and through the API. Personal folders are decryptable only by their owner and a designated recovery account.

Encryption is authenticated AES-256-GCM with random IVs, per-secret salts, 256-bit object keys, PBKDF2 at 600,000 iterations, and HKDF-SHA256 key derivation. Tampering is detected rather than silently decrypted. Existing vaults migrate lazily on first read, with no maintenance window required.

Key capabilities include:

• Security Posture Dashboard scores every user out of 100 and surfaces weak, reused, breached, and overdue credentials, with optional Have I Been Pwned checks
• Linux password rotation (LAPR) changes local account passwords over SSH, agentless, recording only passwords the target machine has already accepted
• Governance tools cover access recertification campaigns, rotation policy tracking, leaver risk detection, four-level data classification, and CSV evidence export for auditors
• Secure Send shares a credential outside the vault under an expiry, a view limit, and an optional passphrase
• Identity integration supports LDAP and Active Directory with nested groups, OAuth2 SSO, and configurable TOTP
• Migration imports from Bitwarden, KeePassXC, LastPass, 1Password, and CSV; exports to KeePass 2.x XML
• REST API with Bash and PowerShell clients for scripted credential delivery into pipelines

Teampass has been validated against GDPR, ISO 27001, and ISO 9001 requirements by real organizations. It's a practical fit for IT teams managing thousands of accounts, small charities that need internal control without cloud exposure, and regulated businesses that need audit evidence on demand.

The server is free with no seat limits. A paid browser extension (from €49/year) adds autofill, password capture, and domain matching across Chrome, Firefox, and Edge. Unlike tools such as Passbolt, there's no feature-gated enterprise edition, everything in the server is available to everyone running it.

Complete control over your passwords with zero cloud dependency. PearPass is an open-source password manager that stores credentials exclusively on your devices, eliminating server vulnerabilities and maximizing privacy.

• Local-first storage - Your passwords never leave your control or touch external servers
• Peer-to-peer syncing - Seamlessly sync across devices without compromising privacy
• Robust encryption - End-to-end encryption using Libsodium cryptographic primitives
• Security audited - Independently reviewed by Secfault Security for cryptographic integrity
• Built-in password generator - Create complex, secure passwords instantly
• Lightweight design - Easy installation and intuitive interface for effortless password management

Perfect for privacy-conscious users who want enterprise-grade security without surrendering data control. The open-source architecture ensures transparency and customization while maintaining the highest security standards through proven cryptographic methods.

Psono is a self-hosted password manager built specifically for organizations that need control over where their credentials live. Instead of trusting a third-party cloud vault, you run the server yourself, keeping encrypted data behind your own firewalls. It's also available as a managed SaaS option if you'd rather skip the infrastructure work.

Vault data is encrypted on the client before it ever reaches the server. That means even if someone gains access to the server, they get ciphertext, not credentials. Encryption happens at multiple layers: client-side, in transit, and at rest.

Key capabilities include:

• SAML and LDAP integration for connecting to existing identity providers and directory services
• Audit logs so you can track who accessed or changed what
• Compliance policies to enforce password rules across your organization
• Encrypted sharing lets teams share credentials without exposing plaintext
• Cross-platform access across Windows, macOS, Linux, iOS, and Android, with browser extensions for Chrome, Firefox, and Edge
• Admin client for centralized management of users, groups, and permissions

All business features are free for teams up to 10 users, which makes it practical for small organizations to evaluate it fully before committing. Larger teams can self-host without per-seat licensing pressure, or contact the team for supported SaaS plans with SLAs.

Compared to tools like Bitwarden or Passbolt, Psono leans heavily into enterprise compliance and directory integration out of the box. The fully auditable codebase means your security team can verify the encryption implementation rather than taking it on trust, which matters in regulated industries.

The source code is publicly available, and the architecture is designed so security doesn't depend on obscurity.
