I figure that the administrators of your homeserver could see your IP address, I doubt that it would be sent to anyone you are just chatting with.

I was thinking about that too, I cant think of much this ID is good for other than fingerprinting users. It just sucks that there isnt much of anything that can be done about it without a rooted device or privacy rom.

I did a internet search on “AAAD” and I found this github repository. I’m not sure if it is the same, but they seem to serve the same purpose and share the same name. I took a look into the code and I saw something about Settings.Secure.ANDROID_ID in AboutPaymentActivity.kt, so I did some searching on that, and according to a person on stackoverflow, Settings.Secure.ANDROID_ID is a ID unique to every app on your phone, this ID will persist across uninstalls and reinstalls. The only reason it should change is if the package name or signing key changes. Also it should be different for different users on the phone, but im guessing it might not be possible to add more users on android auto, im not sure, I’ve never really used one.

Now, about circumventing it, you could modify the source code and remove the license verification checks and rebuild, but this might not be legal, I’m not to good with legal stuff, but the license had a few words that suggest it might be non-free, but if software licenses arent an issue, feel free! There is also the option of just resigning the apk with your own key, which should change the ID, I believe you can do this in luckypatcher with one click, but lucky patcher is kind of sketchy and might not be able to work on android auto, I dont know much about them.

I hope this helps, im sorry I couldnt find any like anything that could just reset it and be done with it, maybe someone else might chime in with a more helpful answer.

If Firefox can read it from disk without a password, any other program running as your user can read it from disk without a password. But to prevent this you can encrypt your Firefox profile with a password.

When your browser connects to a website, it will tell the webserver what type of browser you are using in the HTTP headers. This can be used for serving a special web page for browsers with quirks, or it can be used to block certain browsers.

It may look something like this:

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:123.0) Gecko/20100101 Firefox/123.0

But you can use an extension like this one to spoof your user agent and send out one that corresponds to a chromium browser.

I use SSH with port fowarding to securely access my services running on my server to anywhere I have internet. Its easy to setup, just expose any device running a ssh server like openssh to the internet, probably on a port that isnt 22, and with key only authentication.

Then on whatever device you want to get your services on you can do like

ssh -p 8022 -L 8010:192.168.75.111:80 user@serverspublicip

Where 8022 is the port of the ssh server exposed to the internet (default is 22), 8010 is the port its gonna bind to on the device you are using the client (it will bind to 127.0.0.1 by default), 192.168.75.111:80 is the address/hostname and the port of where your services are on your local network, and user@serverspublicip is your username and the ip address of where your ssh server is.

You can also use ssh to make a SOCKS proxy in your network like this

ssh -g -D 1080 user@serverspublicip

This will make a socks proxy into your network on your device at 127.0.0.1:1080. All of this can also be done on just about any mobile phone running android by using termux.
