ArcGIS Online includes many security options that can restrict access to new applications like Connect for ArcGIS. One example is the restriction only letting users sign in to applications that have been approved by an organisation administrator.


### Diagnosis

If you are blocked from signing in to Connect for ArcGIS because to the Approved Apps restriction, you will see a message like this: -

> *Access to this application has been blocked. Please contact your administrator to allow access to this app*

Your ArcGIS Online administrator can confirm the setting by going to Organization -> Settings -> Security -> Apps. It is likely that they will see that the "*Members can only sign in to external apps that are approved*" setting is enabled.

### Resolution

Add Connect for ArcGIS to the Approved apps list.

1. Click "**Add approved app**"
2. Enter the Connect for ArcGIS Client ID: bTTQ87sU3RCXvDrs
3. Wait for the name "**Connect** **for ArcGIS**" to appear. Select it.
4. Click **Save**

You should now be able to sign in to Connect for ArcGIS.
