No central collection
Your password vault stays encrypted inside a PNG carrier on your device. Larger files use separate disguised, encrypted file-vault containers.
Cloudless Vault
Vault without cloud sync
A cloud vault is convenient, but it creates a central place where encrypted customer vaults can be collected. BlindLock uses a different model: no central customer-vault database, no automatic vault sync and no BlindLock cloud account for storing your secrets.
Three things needed
Opening requires the file, the password and the right device. If one is missing, the vault stays closed.
Optionally harder
You can also require a security key such as YubiKey, Google Titan or SoloKey.
Who is this for?
- People who do not want a cloud account or sync server holding their most sensitive data.
- Admins and founders who want local control over passwords, recovery material and files.
- Anyone willing to trade cloud convenience for less central attack surface.
What BlindLock does not claim
BlindLock does not replace operating-system hygiene and cannot protect a fully compromised computer during an active session. It reduces the cloud attack vector and binds the vault to your device.
Why "no cloud" changes the shape of the risk
A central cloud vault gathers the encrypted data of many people in one place. That is attractive to attackers, because a single successful breach at the provider reaches a large number of users at once. Recent years have shown that even large, carefully run providers can become the target of such incidents. And once an encrypted vault has been copied, an attacker has unlimited time to try the master password offline.
BlindLock inverts that logic. There is no central collection point containing customer vaults because BlindLock servers never receive them. A provider breach therefore cannot expose a mass collection of vault contents that we do not possess. If someone obtains your carrier file, it still requires your master password and the authorised device's hardware anchor — TPM 2.0, Secure Enclave or StrongBox, depending on the platform.
There is no third-party server and no central vault.
Who BlindLock is for — and who it isn't
A good fit
- People who deliberately want to avoid a central vault repository.
- People with high-value recovery material that should never be synced to a provider vault.
- Admins and founders with credentials that must not land in someone else's database.
Less of a fit
- Teams that expect automatic sharing and real-time sync across many devices.
- Users who want a provider-side password reset. With no vault cloud account or recovery copy, BlindLock cannot reset the master password for you.
- Anyone who wants BlindLock to manage a central backup service. You choose the backup location and keep the recovery phrase separately.
A concrete scenario
Imagine a well-known cloud password service announces an incident: backup copies of encrypted vaults were taken. Customers now have to assume their vault is in someone else's hands and rotate every important password under time pressure.
BlindLock removes the central customer-vault store from that scenario. Your carrier sits where you place it, and a copied file alone does not grant access: the master password and authorised device are still required. This is not a guarantee against every conceivable attack, but it removes an entire class of risk from the picture up front.
Frequently asked questions
How does BlindLock work without a cloud account?
You create and store the vault locally. The carrier file, master password and authorised device must all match. A licence and version check occurs at unlock, but there is no BlindLock cloud account or server-side customer vault.
Who owns my data?
You control the vault and its storage. There is no server-side customer vault or BlindLock cloud account holding its contents. You decide whether to export data or place an encrypted backup in a cloud-synchronised folder.
Can I still move my vault between devices?
Back up the active carrier. For migration and emergencies, also create an encrypted BlindLock backup and keep its recovery phrase separately. File vaults additionally require their container, recovery file and recovery factor. One licence activates one device at a time.
