[DEMO] How to use passkeys to encrypt and share files with FileKey

Free and open source

Use passkeys to encrypt and share files

Store your passkey in a password manager or hardware security key

AES-256 encryption (“Military-grade”)

Zero knowledge, only you can access your files

Offline capable

Can be locally installed (progressive web app)

Your data never leaves your device

Fast, ultra-secure encryption and decryption

No accounts, no tracking, no data collection

A compatible password manager (iCloud, Google, etc) or a hardware security key that supports FIDO2 and PRF (like the YubiKey 5 and Bio Series)

For hardware security keys, your browser and operating system needs to support WebAuthn and the PRF extension.

Note: for software passkeys you have to make sure your password manager supports PRF. Many don’t, including 1Password and Proton Pass. Apple Passwords, Google Passwords, and Windows Hello do though (as long as you are on Windows 11).
