Passphrase Reset

Your passphrase unlocks Affinidi Vault and gives access to your data. If you forget it, the passphrase reset feature provides a secure recovery method.

This method uses Shamir’s Secret Sharing, a cryptographic algorithm that splits private information into multiple parts (“shares”). It ensures sensitive data like biometrics, cryptographic keys, and passphrases remain secure.

Passphrase reset generates three PDF files (shares) from your current passphrase. Each file contains secret phrases. A single file cannot reveal the secret. To recover access, you need 2 of the 3 files combined to reconstruct the passphrase.

How Passphrase Reset Works

Affinidi Vault uses Shamir’s Secret Sharing to enable secure passphrase recovery.

Download the PDF Files

To reset your passphrase later:

• Go to Settings and download the PDF files.

• Enter your current passphrase. After confirmation, Affinidi Vault generates 3 PDF files based on your passphrase.

• Distribute these files securely to trusted people, devices, or locations. You will need them if you forget your passphrase.

Best Practices for Keeping Files Safe

Follow these tips to store recovery files securely:

• Give one copy to someone you trust, such as a family members or friends.

• Store one copy on trusted device, like a laptop or mobile.

• Keep one copy in a secure cloud service, such as Google Drive.

• Print one of the copies and keep it safe in a secure physical location with restricted access, such as a deposit box.
