One-time secret delivery
Seen once.
Then gone.
Send passwords, keys, and connection strings through a link that opens one time, for one person, proven by their mailbox.
Create a secret
Balsoft sign-in to create. Recipients need nothing.
How a handover works
- 01Sealed in your browserThe secret is encrypted with AES-256-GCM before it leaves your machine. The key stays inside the link; the server never sees it.
- 02Proven by mailboxOpening the link sends a one-time code to the recipient's email address, and only there. Five wrong guesses destroy the secret.
- 03Opened onceOne successful view releases the secret and destroys the server copy in the same moment. The link is dead. You get notified.
Zero knowledge: the server stores ciphertext it cannot read. Not even Balsoft. Unopened secrets delete themselves at expiry.
