About this app

VivoKey Vault is a secure file storage app that uses VivoKey NFC implants as the access and encryption key. No passwords to remember. Just tap your VivoKey chip to unlock your most sensitive files.

HARDWARE-LEVEL SECURITY
Your files are encrypted with AES-256-GCM, the same encryption standard used by governments and financial institutions. Unlike traditional apps that rely on passwords, VivoKey Vault uses cryptographic keys derived from your VivoKey implant. If you don't have the chip, you don't have access.

OFFLINE FIDO2 SUPPORT
VivoKey Apex implants with FIDO2 resident keys work completely offline. No network connection or API credentials required. Your cryptographic keys never leave your implant, providing true hardware-backed security that works anywhere, anytime.

NOTHING TO REMEMBER, NOTHING TO LOSE
Passwords can be guessed, stolen, or forgotten. Your VivoKey implant is always with you and can't keylogged. Tap to unlock. It's that simple.

SEAMLESS APP INTEGRATION
Open encrypted PDFs in your favorite reader. View protected photos in your gallery app. Edit sensitive documents in any editor. VivoKey Vault integrates with Android's file system so your encrypted files work with all your apps while the vault is unlocked.

MULTI-CHIP SUPPORT
Register multiple VivoKey chips to the same vault. Mix and match Spark and Apex implants. If you have chips in both hands, either one unlocks your files. Share access with a trusted partner. Never worry about being locked out.

ENCRYPTED BACKUPS
Export your entire vault to an encrypted backup file. Restore it on a new phone using any of your registered chips. Your backup is fully encrypted—safe to store anywhere.
