This ones my fave: https://amiunique.org/fingerprint
It shows the percentages of people who use your same browser features (called similarity ratios), and can determine whether you’re unique in their dataset. Can help for tweaking browser settings to try to make yourself not unique.
Yay, I’m completely unique! I won!
Wait a minute
i used to think that firefox on linux and as plain-jane-generic as you could get besides windows; but no, i’m ultra unique:
Yes! You are unique among the 5084762 fingerprints in our entire dataset.
Somehow safari on an iPhone is also unique.
Check next week or in a new private tab now, prob be unique then too—think Apple’s fuzzing/reporting some noise/junk data for us.
Canvas:

& WebGL:

gotta be noisy, here’s hoping!
EFF updated their site since last check months ago, seeming to confirm theory

Nice (& I’m unique again on AmIUnique)
Attribute number 1 already says 0%. We’re done here.
They basically asked for your name, birth date, and mother’s maiden name, and your browser just gave it to them and offered even more.
Is there no add on, for Firefox, for example, to stop or confuse fingerprinting?
Any suggestions?
For Android.
that’s pretty comprehensive, and similarity ratios show how easy it is to create a unique fingerprint for somebody if you hash a few of these metrics together for example.
I am unique cause I set language to EN-GB :D I guess their dataset is us centric
Same here with en-au, and my fucking timezone.
My Mum always said I was unique.
Now I have proof!
Just being in Australia, and setting the timezone correctly gets you to below 0.6%
😒
dang, even with vanadium on graphene i am very uniquely identified. I suppose it can’t be helped these days.
I am a unique signiture but it also got my OS wrong and couldn’t get my time zone
Y’all I think I won privacy
what does “You are unique among the 5119710 fingerprints …” mean?
all trackers hate this one trick

Unironically a solid way to block a lot of tracking. Although they can still fingerprint you I think.
Nothing makes you more unique than being one of the few people who disable java script
Better a known locked door than inviting them into your home
Honestly I would rather they fingerprint compared to running random code from websites.
Only a handful of data points surfaces by this website come from JS APIs, most are either header-based or some other browser behaviour that is independent from JS
“We know your IP address”. No kidding, that’s how IPv4 works, even if the browser wasn’t
leakingoffering it.
And yet here they are showing me their webpage in darkmode 😒
Really interesting and slightly scary, thanks for sharing!
I prefer https://www.deviceinfo.me/
Interesting that this one doesn’t detect my battery (says it’s blocked) but the one OP posted can see it
iOS and the browser I use block a lot of stuff from being visible, interesting!
I get a blank page?
Well they tried

Yeah that was the one part they were way off on for me
Funny how websites can read the gyroscope. It can also be used as a microphone. https://crypto.stanford.edu/gyrophone/
Madness! This entire shit show should incur a stalking charge. It’s disgusting this is even allowed.
So a prettier and minimal version of https://coveryourtracks.eff.org/ ?
Kinda like they feed Cover Your Tracks to an LLM’s template so you can experience the data in narrative form
(No LLM used when you visit the site, just when they built it, is what I’m guessing here)
This is a much more detailed, less “fear mongering AI” version of the other website. Thanks for sharing!
Your screen is 360 by 640 pixels, rendered at 4x density — which means it is almost certainly a recent, high-end display
GUESS AGAIN, IDIOTS!

This post helped me discover that my SurfShark VPN built-in kill switch does not work within the Android app. My home IP was showing.
I turned kill switch on at the OS level and my IP was correctly showing the VPN IP.
Enable the kill switch in the VPN settings of Android
Your device carries these typefaces, of the seventeen commonly probed by fingerprinting checks. The specific combination of fonts on your device is nearly unique — like a fingerprint made of letters
What the fuck why is my browser telling random websites what fonts I have installed? Shouldn’t that be completely irrelevant to everyone except me and my particular device?
It should be, yes. But browsers like Chrome are literally made by the company that stands to profit from fingerprinting you, so they’re always going to be made to make it easy to do just that. Firefox at least has “resist fingerprinting” option which apparently can limit font visibility to only base system fonts rather than fonts you installed and language-pack fonts. LibreWolf has this on out of the box.
Thats part of how you’re fingerprinted.
So it can know which fonts it can use and your device would be able to display them?
Why doesn’t it just let the site display whatever it wants and let me worry about the issue of whether they display properly
The site could also be set to display whatever font it wants but also set to list standard fonts that also work which the browser can then choose from on the user’s end if the user doesn’t have the first choice font. That way you the user don’t have to worry about it and there is no way to fingerprint by the browser just handing out an entire list of fonts installed on the user’s system. There are plenty of ways to make things like this work, but the incentive is to keep them as they are or to increase uniqueness so people can be more easily fingerprinted.
I definitely have misleading information on there, which is great, but I probably need more.
Does it matter for fingerprinting if the information is misleading? Unless it’s changing dynamically I guess it’s still helps in identifying a user
Yeah, I think there are two problems. One issue is that they profile users both for ads and manipulative algorithmic content, and I’d like them to profile me incorrectly in most cases (except like they are less likely to try to sell people on linux things, that’s a great thing I’d like to keep in the profile). The other issue is that they follow individual users using this fingerprinting, again this can be used both to sell things and to manipulate, but it’s a tad creepier since it tracks how you’re unique even compared to people superficially similar to you.
Ideally, I’d like some extension where I can look at values and either keep them, set them, or randomize them.
Great news. My VPN is working!
I’m not even on VPN and I was located half a country away in Europe
I’m glad it acknowledges explains the impacts of anti-fingerprinting measures. I’ve seen some others assume that a random canvas is unique rather than one of the many people randomising it the same way, leading to a false “unique” assessment.
Your browser appears to be returning the viewport in place of the real screen — anti-fingerprinting at work. The substitution is itself distinctive.
Your browser masked your graphics processor. Firefox and Safari have started returning generic strings — “Mozilla”, “Apple”, “or similar” — instead of the real renderer. The fact that yours did so tells us, with reasonable confidence, which browser you are running. The mask is also a fingerprint.
I like that they covered all the possibilities for the do not track flag, as I saw it as useless from the very start, as by then I realized the honour system didn’t mean shit and it would just be another piece of data.
