  • Uses passkeys, so there is no password to remember
  • Encryption happens on the device
  • XChaCha20 and Argon2id, with a design deliberately small enough to audit
  • Standalone portable executable on Windows, with no installation
  • Depends on browser and device passkey support
  • Losing both the passkey and recovery code means losing access
  • Permanently archived and read-only since September 2025; there will be no more releases
  • Encrypts individual files, not partitions, drives or cloud folders
