Onetime Secret Documentation

Give your team a branded workspace on your own domain, integrate one-time secret links into your own tools, or host the whole thing yourself. Everything past sending the first secret.

On the hosted service: a shared workspace with roles and SSO, and secret links sent from a domain your recipients already trust.

  • Custom domains — DNS validation, branding, and an incoming page for secrets sent to you.
  • Organizations — invite members, assign roles, and review Secret Activity.
  • Single sign-on — Entra, OIDC and SAML sign-in for your organization.

Create and retrieve secrets from scripts, CI pipelines and your own applications.

  • REST API — regional endpoints, authentication, and the full reference at api.onetimesecret.com.
  • Client libraries — official and community SDKs, and which ones support regions and custom domains.

Run the same open-source application that powers onetimesecret.com on your own infrastructure.
