Everywhere else you use the name. The value is never shown again, not even to you. This page is for anyone holding a token or key and wondering where it goes. The Secrets page listing secrets by name, with no values shown ## Why use a secret A token is typed once. It does not appear in an agent's settings, or in a config file you might share. And when it has to be replaced, you replace it in one place. ## Where secrets are used * **In an integration.** A sensitive field, such as a Discord bot's token, takes a secret chosen from a list. See [Integrations](/concepts/integrations). * **In a prompt or a tool's settings.** Write `{{ secret "name" }}` where the value should go, for example an API key in a web request that a tool makes. See [Dynamic content](/concepts/dynamic-content). One thing is not a secret: a provider's API key. You type that into the provider itself. See [Providers](/concepts/providers). ## You can replace a secret, not read it Once saved, the value is not shown anywhere. If you lose the original, create a new token with the service it came from, and replace the secret's value. A secret's name cannot be changed. If you need a different name, create a new secret. ## When a change takes effect | Where the secret is used | When the new value is used | | -------------------------------------------- | ---------------------------- | | In a prompt or a tool's settings | The next time the agent runs | | In an integration, or in an entry's settings | After you next save an agent | So after you replace a token that an integration uses, open any agent and click **Save**. ## Deleting a secret Whatever uses a deleted secret fails the next time it runs, and ServFlow cannot tell you in advance what that is. Check your integrations and prompts first. ## Secrets in the dashboard **Secrets**, in the sidebar under **Configure**, lists your secrets by name, never by value. Click **New Secret** to add one. In an integration's dialog, a sensitive field lists your secrets, and **Use a stored secret instead** switches an ordinary field over to one. An integration dialog with a stored secret chosen for the private key field ## Related Use a secret in an integration's field. What an integration is and where it is used. Where a model company's key goes. Where secrets are stored, and how they are encrypted.
