Prevent Candidates from Using Mobile or Tablet Devices

Testlify lets you restrict assessments to desktop and laptop devices only. When enabled, candidates who attempt to open the assessment on a mobile phone or tablet are blocked and prompted to switch to a compatible device before they can start.

Before you begin

• Have an existing assessment open, or create a new one — this setting can be applied at any point.
• Inform candidates in advance that they must use a desktop or laptop. Anyone opening the link on a mobile or tablet will see a device restriction message and cannot proceed until they switch.

Enable the Device Restriction

1. Log in to your Testlify workspace.
2. Open the assessment you want to update — create a new one or select an existing one to edit.
3. In the assessment editor, go to the Settings tab.
4. Check the box labelled Prevent candidates from using mobile or tablet devices.
5. Click Save. The restriction applies immediately to all candidates who access the link.

What happens after saving

Any candidate who opens the assessment link on a mobile phone or tablet sees a message instructing them to switch to a desktop or laptop. They cannot start or submit the assessment until they comply.

Tip: Add a reminder in your invitation email that a desktop or laptop is required. This eliminates last-minute confusion and reduces support requests on assessment day.

Important considerations

• Assessments with Video, Coding, Typing, or Google Workspace questions are already incompatible with mobile and tablet devices. Enabling this setting makes the desktop-only requirement explicit and consistent across all question types.
• Assessments without these question types can normally run on mobile or tablet. This setting overrides that default and enforces desktop-only access for all candidates.
• Always advise candidates before the assessment day so they can prepare a compatible device.
