Best Ways to Implement Like Button Functionality Without User Login

Honestly, without user login, it’s pretty tough to reliably identify users. You might consider using third-party options like the Facebook like button, but keep in mind that users will still need to be logged into those services to use it. It’s a potential workaround, but has its own limitations.

If you want to avoid the complexities of user tracking, just counting the hash of the IP along with some user agent details might be a decent, low-effort approach. Keep it simple, especially since you don't need a bulletproof solution.

Combining a cookie or local storage variable with an IP hash and other browser fingerprinting could work to identify users with reasonable accuracy. Just remember, it won’t be as reliable as having actual logins, but for your needs, it might be acceptable.

You seem to be approaching this like an engineer! If you're aiming for a login-less solution, consider using device fingerprinting along with local storage. It won't be perfect, but it offers some level of user engagement without the hassle of identity checks.

You could implement user fingerprinting as a method, but this varies by device and browser. Another option is to save the liked content ID in cookies or local storage and check that on return visits. While it's not foolproof, it could help manage likes without a login system if you combine it with IP hashes.
