I am fully aware of what vpn services to use and not. I am not using Express VPN, I am simply doing research for a master thesis, when I came across these results from Express VPN. If you have any ideas or corrections, please let me know why a VPN provider would need to have access to these permissions.
Screenshot is from Exodus service, which let’s you view what exactly perimissions and trackers each app uses. You can check out the results and the tool for yourself here: https://reports.exodus-privacy.eu.org/en/reports/com.expressvpn.vpn/latest/
Camera could be taking pictures of QR codes to make it easier to set up a VPN.
Bluetooth could be integration with things like Yubikeys for authentication.
Dunno if that’s what they’re actually for, though.
Best practices would not require camera permissions to scan qr codes.
Scan barcodes
Android includes support for the Google Code Scanner API, powered by Google Play services, which allows you to decode barcodes without declaring any camera permissions. This API helps preserve user privacy and makes it less likely that you need to create a custom UI for your barcode-scanning use case.
The API scans the barcode and only returns the scan results to your app. Images are processed on-device, and Google doesn’t store any data or scan results.

I’m going to assume they didn’t implement this because money. Their app runs on everything, from iOS to Android to Windows. Cost savings they likely just flipped camera permissions and didn’t care about small edge cases like these.
With that said, Mullvad is a million times better, cheaper and doesn’t require even an email or account creation to use. They created a system that effectively anonymizes the user before they even subscribe.
5$ per month isnt cheap for a vpn.
To be fair, they didn’t offer that level of granular control for a while.
If you’re a company with development prioritization that makes it difficult to say “we need to take a few weeks of not working of things that make money to reimplement something we already have that works, because of best practices that don’t make us any money” then it can be really difficult to make changes like that.You don’t want to scan secure QR codes through Google APIs. You can be at risk of Google stealing the contents.
Then use zxing API
But you’ll need access to the camera then.
Doesn’t it use IPC? So only separately installed barcode scanner needs camera.
Mate, you need to give access rights to someone. The camera won’t open magically. The reality is that it’s safer to do everything inside your app, especially when you advertise security.
That must be a pretty new API, right?
Since 2015 it was possible with Mobile Visions API.
Now it’s included in ML Kit
Wow, that’s wild that I’ve managed to miss that.
Was it possible to run it sans-camera permission back then as well?
Thanks for letting me know about it, anyhow.
Well TIL; thank you for that!

I think you can use some of microG’s APIs without connecting it to google.
It’s just not implemented yet: https://github.com/microg/GmsCore/issues/2018

Ah okay that might justify the camera permission, although personally wouldn’t see the need to have that.
Would definitely prefer to see it be an “as needed” basis, like ask every time
That is probably possible, since Android usually asks about that nowadays.
I don’t imagine express is wireguard under the hood but that’s a pretty common wireguard configuration method.

I don’t get why the entire world isn’t on Mullvad.
I don’t trust these guys at all. I trialed them and despite their full money back guarantee, they locked me into a support loop, always switching support staff with boiler plate responses and links that dealt with account issues or whatever. It wasn’t until I left a stern reply demanding the refund or I would escalate the matter with the proper regulatory bodies.
It took 4 support tickets. To me, they came across hella shady.
Dilly dilly, Mullvad is great. I prefer it over ProtonVPN just for how lightweight and simple it is
I know this isn’t popular but I really like Nord. I’ve been with them for years before the ad campaigns that turned people off. Mullvad can use wireguard so I may look at them again at some point, but the Linux cli client for Nord is really solid and picks the fastest server in whatever region you like.
Wireguard is insanely fast. Like insanely fast compared to traditional VPN connections. For me that is an absolute dealbreaker they don’t have it.
Once you start using Wireguard you can’t go back.
Thanks for the update. I just checked them out and they seem like they have a lot of servers. They’re almost double what I paid for Nord. Is there enough of a difference to consider switching? My Nord subscription doesn’t expire for five more months though.
Mullvad is by far the best for privacy since you can literally pay with cash and all your account is is a number. No email, no phone number (unless you pay with Swish), nothing at all identifiable except your IP.
The pricing is honest and very consumer friendly, although being more expensive than average. There is no subscription, just monthly cost with no special discounts to get you to buy it “cheaper”.
And they got raided by police and provided them with everything they had: Literally nothing.
Up to you. For me it would be about trust. These guys are supposed to be my disguise. And then obviously speed.
I have a 1Gbps line and see no speed impact using Mullvad. Unless I move to real far geographical servers. And even then, some still hit peak throughput.
The anonymity is great too as you can send them an envelope with cash and your account number and they’ll process it. Their service feels like you walked up to someone on the street, got a month’s of VPN and walked off. I wish every sale had to be set up this easy.
Worst thing about mullvad is they only offer like 5 devices or so for your subscription. If they bumped it up to 7 or 8 I’d have no complaints.
For the price, 5 devices is really reasonable
I didn’t say it was unreasonable. I just think it would be nice to have a couple more. I’m usually running out on the devices I run and have to proactively prune connections from machines that might, at the moment, not be using them. What I really wish is that it had tiers: like paying 1 euro for each available connection, versus just “5 euros and 5 connections” - I don’t need 10 full connections, but I’d be happy paying 7 euros for 7 connections.
That depends entirely on your use case, and how “devices” is defined.
For example, I run a couple of docker containers which each have their own VPN connection for different purposes. All connections originate from the same IP and run on the same physical machine even, but if they would be counted as different “devices” that would eat up the 5 device limit rather quickly.
Wait, are you the same guy I asked for access to your draft when you’re done?
How is the paper going? Will you also be covering self-hosted VPNs in your thesis? Also, SSL-VPNs seem to be coming up nicely, so if you’re interested in obfuscation, that might be interesting to you! Can’t wait to read what you’re cooking!
Hahah thats me! :P (lemmy is a small world) My main focus is most likely going to be free vpn’s and the risk of using them. I have to limit the scope quite a bit and want to cover areas that are not that well properly documented… yet…
But thanks for the tips! I will defo read up on it and see wheter or not I can have a “alternatives” section towards the end.
Edit -> This research paper might feed your temporary needs :P https://www.usenix.org/system/files/usenixsecurity23-ramesh-vpn.pdf
Thanks, downloaded! Keep up the excellent work!
I use Express VPN and the camera permission is relatively new as I don’t have it enabled and it’s never asked me prior to enable it. I dug through the app and found it within their new password manager when you add a new credentials it offers you to help setup 2FA with the major providers and you can optionally scan a QR code with it so it’s a benign convenience feature.
Bluetooth on the other hand I cannot explain unless it’s to proxy any connections Bluetooth devices might make.
thanks for the insights :)
Not an endorsement of ExpressVPN, I’ve learned to avoid companies that sponsor on youtube. However, I believe you don’t need the proprietary app to use the service, you could use a free software OpenVPN client such as this one.
They do offer support for OpenVPN although, unsurprisingly, they heavily push their proprietary client as the preferred way to use the service. This alone would be enough to discourage me from using it or recommending it.
If handfuls of youtube sponsor callout videos has been proof of, is that you should never use a service advertised on youtube.
Kindly enlighten us good sir.
Any money spend on marketing is not used to improve the product.
So, not advertising is the best advertisement for intelligent consumers?
Yes. See Sennheiser versus Beats.
There are Bluetooth FIDO security keys out there for 2FA, like: https://thetis.io/products/fido2-ble-security-key. Some implementations can also use a phone, running an app via BLE. Not sure if they use it, but that could be one reason it’s asking for that permission.
Camera permission may be needed for scanning QRCodes to set up 2FA.
I prefer mullvad. Not only is their pricing and account system much more privacy focused, they are a European (Swedish) company and are bound by the laws of my country by default. Another European one is surfshark (Dutch) which I used before. I trust mullvad more though. They also have open source clients and had no user data stored when they were raided once before.
Edit: clarifying the reason I used surfshark. I used it back when I was in high school a few years ago, so their 3 year plan seemed like a very good price. They also supported this very obscure VPN protocol whose name I can’t remember, and my school just so happened to have forgotten to block it on their network. But I couldn’t use that protocol on Linux due to incomplete connection steps provided by surfshark, and I switched to using linux full time in the second half of my first year, so that was a waste and I just used my mobile data.
They also push the envelope on privacy, and frequently publish security reports.
not to discredit what they do and what’s been said, but i think it’s important to keep in mind (with one’s threat model in mind also) that they’re based in Sweden, a 14 eyes country.
What’s 14 eyes?
basically an agreement between 14 countries to share signals intelligence amongst one another. effectively, if your data gets captured in Sweden, all the participating states are able to get their hands on it. check out the Wikipedia article for more details on 14 eyes: https://en.wikipedia.org/wiki/Five_Eyes#Fourteen_Eyes
Thank you.
In the mobile space, there are Chinese calculators apps on Androids by manufacturers that require internet access…
To be fair, the calculator on my phone has a built in currency converter and would need network access to get the exchange rates
That’s legit and justifiable though I rather my apps to perform just one core duty and don’t unnecessarily append unnecessary functions to justify internet access.
And the calculator apps I’m referring to doesn’t have currency function. I only found out when I use root and XPrivacyLUA to monitor apps permissions some years back for context.
I know the camera permission can be explicitly denied by you, and the app can’t work around that. As for Bluetooth, I think it’s the same story, although I haven’t checked …
This isn’t an endorsement of the VPN service, as other people have pointed out it has some issues
lol

Don’t use ExpressVPN, they and others make money off of your data.
My eyes… ouch
Oof
