Troubleshooting: Salesforce1 App Does Not Recognize Device Fingerprint

Version Affected: All
 
 

Overview

The Salesforce1 mobile app does not honor a device's stored fingerprint, so users are prompted for two-factor authentication every time even though a fingerprint has already been logged for their device.

Cause

The Salesforce1 app does not accept cookies, so when SecureAuth tries to match the device's fingerprint ID with a cookie ID, the match always fails.

Resolution:

To resolve this:

Change the device fingerprinting settings so SecureAuth no longer tries to match the fingerprint ID to a cookie ID. At minimum, change the following two settings:

• Under System Components, lower Host Address/IP from 15% to 5% or less.
• Under Mobile Settings, change Match FP Id in Cookie from True to False.

The following settings are optional, but make authentication more flexible:

• Under System Components: Timezone to 6%, Screen Resolution to 10%.
• Under Mobile Settings: Authentication Threshold to 90%, Update Threshold to 85%.

Special Considerations

Lowering these thresholds makes the second-factor bypass more lenient, which reduces security. Find the right balance between security and convenience for your environment before changing these settings.
