What can someone I give my WiFi password to (e.g. girlfriend/boyfriend) read?
Could he read my passwords?
or keys that I press?

Does a mobile internet box work if there is no reception?
Good day, I've just moved into an apartment where unfortunately, there's no internet connection yet. It wouldn't be a problem if my mobile internet worked (Aldi Talk flat rate). Unfortunately, the internet barely works, if at all. I'm assuming the reception is poor because the walls are very thick. My question is, would a mobile…
Telekom threatens to blacklist me as a contractual partner?
BySolairee
My DSL contract with those guys in purple is about to expire and I want a new contract. I don't care whether I get a new phone number or not. I don't use a landline anyway. So I would simply cancel my current contract and then start a new one a week later through a…
Search history confronted what to do?
Hi, My parents told me today that I use reputable websites because they received a letter from my internet provider. My problem is this: I don't watch porn, but I do watch football, series, or things like that on illegal websites, which then lead to such websites because no matter where you type, such websites…
Network cable only recognizes router, not my computer?
Hey, The following question: how can it be that my computer does not recognize the LAN cable, but as soon as a repeater (Telekom) is plugged in between, it works? I have a Telekom Speedport Pro Plus router. It's connected to a 1Gb switch that handles the distribution to the rooms. When I connect my…
I supposedly registered somewhere?
I just received a text message and a WhatsApp message saying I've supposedly signed up with leichtuder. I'm reading that I'm not the only one, but they know my email address, where I live, and my name. They're also demanding payment. What should I do?
How to lay LAN cables differently?
Hello, as you can see from the pictures, the LAN cable is only a temporary solution – a friend said that from the cupboard where my Fritzbox is, you could lay the cable along the wall over the wardrobe and secure it – now my only question is: how do I best run the remaining…
In the meantime, virtually all data are transmitted encrypted via TLS, so you can’t really start a lot, you can analyse at most where the data go but don’t read the data yourself.
Why should key presses go over the network? Think about it, too, that it would be crawling.
That. Access to a wlan or an open wlan is no longer as critical as before. The biggest risk would be more likely to be your friends/recognition e.g. Illegal filesharing is of course the mail to the connection owner, even if it is not liable for others, it is of course annoying.
Of course, if you do stupid things like giving folders for your pc free for the local network, you can see them of course. Something like that happens, but that’s your own failure.
I’m interested in the friends/known whom I make available my Wi-Fi, which could also read out any passwords. So somehow come in my PC => could
No, that’s not a problem in general.
Not if the page on which you enter your password has done your homework.
No, your friend would have to install a keylogger.
Yeah.
Happiness has now prevailed across the board.
But even this already presupposes some criminal energy, just that doesn’t happen.
would a VPN make this better?
Then you could only see that you connect to a VPN… but you could just refer friends to the guest WLAN.
yes from the guest WLAN I read something earlier. I’ll have to look and maybe get in. Thank you.
As long as you use websites that use https, other users in WLAN cannot read your passwords. Pretty much any site that uses passwords nowadays uses https. Unencrypted websites are becoming increasingly rare.
However, there are always some metadata (e.g. data volumes, visited websites/target hostes, DNS requests etc.) that can also be read in encrypted connections. These metadata may be used to make some assumptions, for example about which devices you use when you are active or what your interests are.
Therefore, it may make sense to encrypt the traffic additionally via a VPN if people are in the WLAN that you do not want to trust 100%.
If you have enough computer knowledge, you can filter and monitor all internet traffic from your phone or laptop or desktop PC or a specific device.
My brother programes websites and if I have problems he fixes my computer before I have noticed anything at all.
My brother lives 800 km away from me.
Normally, everything is not going, because that would be criminal.
Nothing – with Password is what goes through the WLAN encrypted.
You need access to the router. Or you have to play-in-the-middle, so that your complete traffic runs over their computer.
Then you would use their Wi-Fi, not yours.
So no one can grab my PC just because it’s in my WLAN?
or it has a 3th person access to the router
In order to access the router directly, you usually need an administrative word.
