This service lets you send email attachments securely and receive them the same way — no passwords, ever. When you send a file, it's removed from the email before it ever reaches an inbox, and the person you sent it to can only open it after proving who they are with a passkey (their device's fingerprint, face, or a security key).
How it works, in short
- You send an email with an attachment, exactly as you always have.
- The attachment is removed before the email reaches an inbox.
- The recipient gets a short notice instead, with a retrieval code.
- They register a passkey the first time — no password, ever.
- Every visit after that is a single tap to open what was sent to them.
