OneTimeSecret turns a password or private note into a single-use link that destroys itself the moment the recipient opens it. Create a secret in seconds from the web form: paste the text, optionally lock it behind a passphrase, and pick how long the link stays alive, from minutes to days. Send the generated link by email straight from the app, or drop it into any chat or ticket where a credential needs to change hands. Because the link burns after one view, a forwarded message or an old thread search cannot leak what was shared; once the recipient reads it, the content is gone for good. An API issues secrets programmatically, so scripts can hand database passwords or access tokens to teammates without writing them into CI logs or shell histories. Use it anonymously for quick one-off shares, or switch on full authentication with accounts, multi-factor authentication, and WebAuthn keys for a controlled internal service. Custom domains let the links carry your own hostname, so recipients see a service your organization operates rather than a public website. Admins manage users, domains, and access from a built-in console suited to teams that hand over credentials every day.
