Solution 1Recommended

Consult Microsoft Q&A SharePoint Development

Since the AppRegNew.aspx interface changes are related to Microsoft's underlying SharePoint development updates and deprecations, reaching out to official developer support is the most effective solution.

Microsoft frequently updates its security and app registration processes. The legacy Generate controls on appregnew.aspx may be restricted, disabled, or transitioned to Microsoft Entra ID (formerly Azure Active Directory) for newer tenants.

Frequently Asked Questions

Why are Client ID and Client Secret missing on AppRegNew.aspx?

Microsoft has been deprecating legacy SharePoint App-Only authentications (ACS) in favor of Microsoft Entra ID (Azure AD). For many newer tenants, the traditional Generate buttons on AppRegNew.aspx are disabled by default to enforce modern security standards.

Where should I register apps for SharePoint if AppRegNew.aspx is restricted?

You should typically use the Microsoft Entra admin center (Azure Active Directory) to register your application, generate client credentials, and grant the necessary SharePoint API permissions.

Can I still use Office365-REST-Python-Client with modern authentication?

Yes, the Office365-REST-Python-Client library supports modern authentication methods, including MSAL (Microsoft Authentication Library) and Entra ID certificates, which bypass the need for legacy appregnew.aspx credentials.
