Can Quackr see my passwords?

Short answer

No. Your vault is encrypted on your device with a master password we never receive, using the open-source, independently audited Passbolt engine.

Zero-knowledge means the unlocking happens on your computer or phone, never on our servers. What we store is encrypted data we hold no key for.

The engine underneath is Passbolt, which is open source and independently audited. You don't have to take our word for how the encryption works: anyone can read the code.
