How It Works for Your Users
When Users Login
● The plugin automatically detects and registers their device
● Each device gets a unique fingerprint based on browser, OS, and other factors
● Users can login from up to your set limit of devices
When Device Limit is Reached
● Users trying to login from a new device will be blocked
● They’ll see a clear error message explaining the limit
● They must contact you to reset their registered devices
Device Management for Users
Add the shortcode [my_devices] to any page to let users:
● View their registered devices
● See device details (browser, OS, last login)
● Remove non-primary devices (except their first registered device)
Admin Features
Device Management Dashboard
● Users > Device Limit: Main management interface
● View all users and their device counts
● See detailed device information for each user
● Reset devices for individual users
● Monitor users who have reached their limit
Troubleshooting
User Can’t Login After Browser Update
Cause: Major browser changes may alter device fingerprint
Solution: Reset user devices – this is rare but can happen
Plugin Not Working
● Verify license is active and valid
● Check that you’re not testing with admin account (admins bypass device limits)
● Ensure JavaScript is enabled (required for admin interface)
Best Practices
Communication with Users
1.Set Expectations: Clearly explain device limits during registration
2.Provide Instructions: Create a “Manage Devices” page with the shortcode
3.Support Process: Establish clear process for device resets
Recommended Pages to Create
● Device Management: Page with [my_devices] shortcode
● Device Policy: Explain your device limit policy
● Support Contact: How users can request device resets
Remember: This plugin requires users to enable cookies for proper device tracking.
Important Notice
Before You Purchase
This plugin provides solid device limiting functionality for small to medium WordPress sites. However, it’s important to understand these limitations to ensure it meets your specific needs.
Technical Limitations
Cookie Dependency
● Device tracking relies on browser cookies – Users who frequently clear cookies or use private/incognito browsing may need device resets more often
● Not suitable for environments where users regularly clear browser data or use shared computers
Device Detection Accuracy
● Browser updates may occasionally change device fingerprints, requiring device resets (rare but possible)
● Similar devices on the same network may sometimes generate similar fingerprints
● VPN usage by users may complicate device detection
This plugin provides reliable device limiting for most small to medium WordPress sites. While it has limitations, it offers a solid foundation for preventing account sharing without being overly complex. The limitations listed above are common to most device-limiting solutions and reflect the inherent challenges of device detection in web environments.
