High Assurance with MFA Error

Problem

Salesforce requires Multi-Factor Authentication (MFA) for all users. This means "High Assurance" setting in Session Setting is enabled by default. However, "High Assurance" being enabled restricts the asynchronous processing performed by S-Docs Jobs and causing them to fail or produce corrupted files.

A common manifestation of this can be the ‘Failed to load PDF’ error when an S-Docs Job successfully completes and generates a PDF template.

Solution

1

Navigate to the Setup menu in your Salesforce Org.

2

Type "Profiles" into the QuickFind bar and then click Profiles in the dropdown menu.

3

Click Edit next to the appropriate profile name.

4

Find the Session Settings section, and ensure the Session Security Level Required at Login is set to None (not High Assurance).
