# Enable the Authorization Code and Credentials Flow

The Authorization Code and Credentials Flow is the foundation of headless login and headless registration. Enable this flow at an org-wide level.

|Required Editions|
|-----------------|
|Available in: both Salesforce Classic (not available in all orgs) and Lightning Experience|
|Available in: **Enterprise**, **Unlimited**, and **Developer** Editions|

1.  From Setup, in the Quick Find box, enter `OAuth`, and then select **OAuth and OpenID Connect Settings**.

2.  Turn on **Allow Authorization Code and Credentials Flows**.

    You receive a warning that changing this setting can break your integrations.

3.  To accept the warning, click **OK**.

    With this flow enabled, you can access settings to turn it on for a specific external client app.
