tasks:</p> <ul><li>To execute an OIDC exchange with Identity Engine that checks if the user signed in successfully.</li> <li>To validate user ID and access tokens locally after they’re retrieved from Okta. See <a href="#validate-tokens-locally">Validate tokens locally</a>.</li></ul> <p>To initiate the OIDC exchange, use your preferred OIDC library.
