How can I make it more difficult for a user to create multiple accounts in my website?

[Shield]

I would like to know the best way to increase security on a website so that the a single user can't create multiple accounts.

What all of a user can be traced? I'm thinking:

• IP address
• Mac address
• Browser details
• Computer name and its details

I know an IP address can be spoofed but is there a work around to still identify a banned user? Maybe a combination of IP, MAC, and computer details?

Can we ban users on the basis of their MAC address? Is there any other way to trace them to stop them creating multiple accounts?

You maybe want to check out this Project https://valve.github.io/fingerprintjs/

Fingerprinting is a technique, outlined in the research by Electronic Frontier Foundation, of anonymously identifying a web browser with accuracy of up to 94%.

To reduce multiple account creation, combine methods like tracking IP addresses, browser fingerprints, and device info (user agents, screen size). MAC addresses can't be reliably accessed via web browsers due to privacy restrictions. Use email or phone verification and CAPTCHAs to deter bots. Behavioral analysis can help detect suspicious activity. While IPs can be spoofed, combining multiple signals increases accuracy. Remember, no method is foolproof, but layering these strategies improves security and user traceability effectively.
