What C2 Password Is (in plain English)

C2 Password is Synology’s cloud password manager that keeps all your logins, notes, and sensitive details in one safe place and makes them available on every device you use. It generates strong passwords, autofills them when you sign in, and checks your vault for weak or compromised items so you can fix issues fast. Under the hood, everything is protected with end‑to‑end encryption, and the keys stay with you — not on Synology’s servers. That’s the “zero‑knowledge” idea in practice. (c2.synology.com)

Why Back Offices love it

• It replaces risky spreadsheets and shared inboxes with organized, permissioned vaults. Teams see only what they should, while personal items stay private.

• Onboarding and offboarding get simpler: add people to the right shared vaults on day one, then remove access in seconds when roles change.

• Built‑in health checks surface reused, weak, or breached passwords — a quick win for security audits.

• It scales from a single admin and a few users to larger teams, and it plugs into Synology’s identity tools when you need centralized user and device management. (c2.synology.com)

The security model (short and sweet)

• End‑to‑end encryption (AES‑256): Items are encrypted before they leave your device and remain encrypted in transit and at rest.

• Keys stay on your devices: The decryption key isn’t stored on Synology’s servers, so only you and the people you authorize can read your data.

• Zero‑knowledge design: Synology can’t view your vault contents.

These are the fundamentals you want backing your Back Office. (c2.synology.com)

What you can do day to day

• Generate and autofill strong passwords for websites and apps to save time and reduce errors.

• Store more than logins: keep secure notes, IDs, and other sensitive items neatly organized with categories and tags.

• Run a password health check to spot risky items and get recommendations to fix them.

• Use the built‑in Authenticator (TOTP) to keep 2FA codes with their logins.

• Share safely: invite people to a shared vault, or send a temporary, limited‑recipient share when someone outside your org needs a credential briefly. (c2.synology.com)

Plans that fit how you work

• Free: 1 user, unlimited devices, core features like generator, autofill, cross‑device sync, and health checks.

• Plus: designed for families or very small teams (1 admin + 5 users), with a private vault per user and one shared vault.

• Business: for growing teams (10+), with unlimited shared vaults, admin controls for users and vaults, and integration with C2 Identity Business for directory/SSO‑style management. Each user gets up to 10,000 items and 100 MB for secure attachments. (c2.synology.com)

Platforms and where it runs

• Web, mobile, and extensions: Use C2 Password on iOS and Android, plus browser extensions for Chrome, Edge, Firefox, and Safari. Sync is unlimited across devices. (c2.synology.com)

• Up‑to‑date extensions: Official add‑ons are available on the Chrome Web Store and Firefox Add‑ons, with autofill, autosave, and generator built in. (chromewebstore.google.com)

• Data residency choice: Choose to host your vault in the US (Seattle) or EU (Frankfurt) regions — helpful for policy and compliance needs. (c2.synology.com)

Sharing that doesn’t create chaos

• Shared vaults keep team credentials in one place with clear membership and permissions.

• Temporary item sharing lets you send a specific item to outside recipients without giving them vault access. Limits help keep sharing tight (1 recipient on Free, up to 20 on Plus/Business).

This is exactly the kind of lightweight access control that makes Back Office processes cleaner. (c2.synology.com)

How it supports a solid Back Office foundation

• Standardize credential management: One tool, one process, less shadow IT.

• Speed up people ops: Provisioning credentials by team (finance, ops, support) takes minutes and scales as you grow.

• Reduce helpdesk tickets: Autofill and strong password generation cut down resets and lockouts.

• Be audit‑ready: Health checks and structured access make it easier to demonstrate good password hygiene.

• Integrate when you’re ready: Pair with C2 Identity Business for centralized user/device management, directory integrations, and SAML SSO — with C2 Password Business features included. (c2.synology.com)

Quick recap

• Secure by design (end‑to‑end encrypted, zero‑knowledge).

• Simple to roll out across web, mobile, and all major browsers.

• Built for teams, with shared vaults, temporary sharing, and admin controls.

• Grows with you, and ties into Synology’s identity platform when you need enterprise‑style control. (c2.synology.com)
