How to fix the Salesforce OAuth Error

This page is for the Salesforce OAuth Error screen. The message includes OAUTH_APPROVAL_ERROR_GENERIC. You may see this screen when you connect Mobile Locker to Salesforce or Veeva.

Salesforce has not approved the Mobile Locker app. A user cannot fix this. A Salesforce administrator must install the app.

Install the app

A Salesforce administrator follows these steps:

  1. Go to Settings > Apps > Connected Apps > Connected Apps OAuth Usage.
  2. Find Mobile Locker in the list.
  3. Click Install. Follow the prompts.

If Mobile Locker is not in the list, ask the user to try the login once. Then refresh Connected Apps OAuth Usage.

Try the login again

After the administrator installs the app, connect Mobile Locker to Salesforce. Open this URL, or your company login URL:

https://app.mobilelocker.com/login/salesforce

In August 2025, Salesforce required administrators to approve connected apps again after a security incident. That is why this approval is required.
