Applications > An OAuth Application > Client Secret > Reset
Single Sign-on allows you to reset the Client Secret for the OAuth applications. Public clients do not use client secrets. In OAuth Advanced Settings, if you enable Public Client, Single Sign-on automatically removes the client secret from the OAuth application. Single Sign-on generates a new client secret whenever you save the OAuth application if there is no client secret. The only exception is when you enable public clients.
To reset an OAuth client secret:
On the Applications page, select the appropriate OAuth application to edit.
At the end of Client Secret, select Reset.
Select Save and Single Sign-on generates a new client secret for the OAuth application.
