mayfly Send

Share a secret that self-destructs when it's read.

The human version of what mayfly does for your AI agents' credentials.

Zero-knowledge: we only ever store ciphertext we can't read. The decryption key stays in the link and never reaches our servers.

How it works

  1. 1

    Encrypt in your browser

    AES-GCM runs client-side. The key lives in the link fragment and never touches the network.

  2. 2

    Share a one-time link

    Send it however you like — only whoever opens the link can decrypt the secret.

  3. 3

    It burns on read

    The first open destroys the secret; a second visit finds nothing. Unread links expire at their TTL.

Doing this by hand? mayfly automates it.

You just used an ephemeral secret. mayfly gives your machines the same thing — credentials that exist only as long as they're needed, then die.

For teams → mayfly-cloudCentral policy, audit, and budgets for every credential your org's agents touch.For developers & AI agents → the mayfly CLIBroker short-lived credentials to your agents and CI — automatically, no copy-paste.
