VaultLink is built for the moment you need to share a credential but don’t share the same password manager. Unlike shared vaults, it requires no accounts on both sides and no permanent access. Unlike simple self-destruct notes, secrets are encrypted and decrypted in the browser, keys never touch the server, OTP is required before reveal, and view limits are enforced atomically. OpenAI keys, Stripe secrets, JWT tokens, SSH private keys — if it shouldn’t live in Slack, it belongs in VaultLink.
