App Password: The app password is created when you first launch the DAU Vault app. It controls access to your DAU Vault app and can be used alongside biometric verification (fingerprint or facial recognition) for added security. Each time you access the app, you will be prompted to enter your app password or use biometric authentication. Additionally, the app password is required for sensitive actions within the app, such as viewing your hot wallets’ private keys or recovery phrases.

Encryption Key: The encryption key is a password you create when backing up your hot wallets to Google or Apple clouds. It encrypts your private keys saved to the cloud. You will need to enter the encryption key when importing a hot wallet from the cloud backup.

You can take unlimited cloud backups, creating a new encryption key each time. This feature mitigates the risk of forgetting an encryption key from a previous backup. Each new backup overwrites the previous one, ensuring your latest backup is always the most current and secure.

Access Code (for DAU Key Card only): This additional security layer is a password linked to your DAU Key cards (only available with 2 or 3 card sets). You set it up during the DAU Key card backup process. You'll need to enter this code whenever you use the physical DAU Key card. Access code is not applicable for single DAU Key cards or hot wallets.

If you have a 2 or 3 card set, you'll also need to tap the physical DAU Key card and enter the access code to perform any actions within the cold wallet, including transactions.
