Which should you choose?
Choose OneTimeSecret if you want open source, self-hosting, a choice of region or an identity-provider plan. Choose SecureVoult if you want secret requests and chat rooms in the same hosted service. Text secrets created on the home page are encrypted in your browser with AES-256-GCM, and the key stays in the link you share. Attachments and secrets with an email notification are still encrypted on our server.
