# Defining a secret
<a name="workflows-working-with-variables-define-secret"></a>

You define a secret on the **Secrets** page of the CodeCatalyst console. For more information, see [Masking data using secrets](workflows-secrets.md).

For example, you might define a secret that looks like this:
+ Name (key): **my-password**
+ Value: **^\*H3\#\!b9**

After the secret is defined, you can specify the secret's key (**my-password**) in the workflow definition file. For an example of how to do this, see [Example: Referencing a secret](workflows-working-with-variables-ex.md#workflows-working-with-variables-ex-refer-secret).
