Are you trying to log in with Salesforce and seeing this error? OAUTH_APPROVAL_ERROR_GENERIC
You are not alone, as Salesforce implemented several security control measures in October 2025, intended to slow the number of bad actors abusing OAuth-connected applications. Here is an official Salesforce blog highlighting the change.
“We can’t authorize you because of an OAuth error. For more information, contact your Salesforce administrator.
OAUTH_APPROVAL_ERROR_GENERIC : An unexpected error has occurred during authentication. Please try again.”
Root Cause for Error for OAUTH_APPROVAL_ERROR_GENERIC New Salesforce Connected Apps
If you are trying to log in with Salesforce for the first time to create a new connected app, this workflow for non-Salesforce admins is disabled. As a result, Salesforce admins will need to install connected apps before non-Salesforce admins can successfully “login with Salesforce.”
How do you know if this is the root cause?
For now, you can look at the URL where the error_description is clear, but simply not rendered inside the page for end users to understand what is going wrong.
Is it a horrible user experience? YES! We hope that Salesforce realizes you can be secure and create clear guidance to non-technical users.
