Session Checker
Enter your session key to check its current status and time remaining.
For Best Results
- Both sender and receiver should be on the same network for fastest direct P2P transfers.
- Transfers across different networks automatically use a TURN relay as fallback — slightly slower but still end-to-end encrypted.
- DropKey stores zero file data on its servers — only encrypted WebRTC signaling passes through.
- Session keys expire after 5 minutes of inactivity. Start a new session if yours has expired.
- For the largest files, use a wired connection or strong Wi-Fi to avoid transfer interruptions.
- If a transfer stalls, DropKey will auto-retry up to 5 times with exponential backoff before failing.
