Zero-knowledge password manager
Understanding our zero-knowledge security model
Passary CANNOT recover your master password or decrypt your vault if you lose access.
This is not a limitation, but proof that our zero-knowledge architecture is genuine. If we could recover your password, it would mean we have access to your encrypted dataβwhich we don't.
Our inability to recover your password is a feature, not a bug. Here's why:
Your vault is encrypted with a key derived from your master password using Argon2id. This key exists only in your browser's memory when you unlock your vault. We never see it, store it, or transmit it.
If password recovery were possible, it would require us to store information about your password on our servers. This creates a potential security vulnerability that could be exploited by hackers, governments, or malicious actors.
Even if Passary's servers were compromised, your encrypted vault would remain secure. Even if legally compelled, we couldn't provide access to your vault because we genuinely cannot decrypt it.
Since we can't help you recover a lost password, it's essential to follow these best practices and understand your responsibilities as outlined in our Terms of Service:
Your master password should be:
π‘ Tip: Consider a passphrase like "BlueSky-Mountain42-Coffee!" instead of random characters like "xK9#mP2@vL7q"
Export your encrypted vault file regularly:
Keep your vault backup in multiple secure locations:
Periodically verify that you can successfully import your backup vault file. This ensures your backups are valid and you remember your master password.
If you forget your master password and don't have a backup, your vault data is permanently lost. There is no recovery process, no backdoor, and no way to bypass the encryption.
| Feature | Passary | Others |
|---|---|---|
| Password Recovery | β Not Possible | β Email reset, recovery keys |
| Data Access by Provider | β Impossible | β Technically possible |
| Government Requests | β Cannot comply | β Must/may comply |
| User Responsibility | β οΈ High | Lower |
Passary prioritizes security and privacy over convenience. If you prefer the ability to recover your password via email or account recovery, a cloud-based password manager might be more suitable for your needs.
