By far the most clear explanation i have ever listened to on youtube about signal and its advantage...damn this guy deserves a sub! Also please do a comparison of whatsapp,telegram and signal since everyone claims the privacy steps taken by them is super good....for a normal user everything is a buttering, only few with a technology background will get to know whats happening behind!
Please do the comparison
Thanks for the push. 🤓 Have you watched ruclips.net/video/MxULcUA4B5U/видео.html
@@sunknudsen no, will check now!
I have switched to Signal and never looked back 🤩!!
Add me
Me too

Great video. Thorough explanation, concise. Much appreciated break down. Subbed.
Good stuff. Talking about the same things on my channel. The more we understand about data privacy the better. Appreciate the work!
You need more subscribers! Your vids have been awesome and very helpful
Thanks for the push. The more people have exposure to this kind of content the happier I am. 🤓
Thank you for teaching!
Very informational. Thank you!
Thank you so much for making this video!
Really interesting and helpful, Sun. Thank you.
Content is Wonderful.....keep making videos on privacy...love from india
Thank you sooooo much for sharing your knowledge.
Liked and subscribed! 😉
Gracias amigo!
Welcome to the privacy guides community!
great explanation. Thank you
Really helpful, thx.
Hey Sun, you said on the first episode that you would tell us how to use Mac´s mail for privacy Please do that one! Thanks for the vlog theyre really helpfull
Thanks for reminding me about that... now that I am out of the rabbit hole, regular programming is back! Will keep that episode on the radar.
Thank you for the information
You deserve more subs
This video is always relevant
Great video. Thanks
Pleasure Hossam!
Just downloaded it. Now, how the hell do I get my friends to download? Explain to them that it's even more secure than imessage? I'm on android btw.
I simply told them that I am moving to Signal, and why. I am not willing to continue to provide any more of my personal data to Facebook for the sake of convenience.
Just send them an invite
Delete WhatsApp they will migrate eventually
They need to put more ads out there so people can learn about signal
@@Acord718 but you do realize that will cost money
Nice information Sun
Hi like your video ,Signal is the most secure instant messaging and calling application that allows users to send messages, voice notes, images, videos, and files to individuals or groups.
Hi Sun; thanks to share this kind of information and knowledge. What about Telegram, what do you this about this solution, it's private? Secure?. Thx.
@Sun Knudsen The videos are great, thank you so much. I would like to make sure I got right what you say at 8:09 : the concept is that since communication is encrypted and you can know for sure who you are talking to, then the information security part (confidentiality, integrity, availability) of the game is relatively full proof. At this point the potential remaining threats are on the operation security side, for example someone can steal your phone and/or coerce you in providing phone access so that the messages can be read on the phone directly. So the threat moves from infoseq to opsec. Is that correct? Would it be correct to say that before signal installation you have both infoseq and opseq potential treats, the infoseq part is removed with signal and you are left with opseq only?
> Is that correct?
Yes, spot on!
> Would it be correct to say that before signal installation you have both infoseq and opseq potential treats, the infoseq part is removed with signal and you are left with opseq only?
There is no silver bullet and depending on the use case, an appropriate answer would be significantly more nuanced. For instance, how secure is the OS? Have you disabled Bluetooth and Wi-Fi? ...
@@sunknudsen that is stil your opinion on the matter?
No one else uses SMS mms or I message in the world except US. Platforms mostly used are whatsapp and telegram etc
What’s the apps that you use on a daily basis in a privacy perspective?
Alternative apps to common ones that are less private
I highly recommend everyone to use signal and also suggest ur friends and family to do the same
13:24 is there any app or any other method to block screenshots? ?
Hey Sun, you mentioned that ephemeral data might be something to go for.
The option you showed on Signal that makes messages disappear after a set amount of time only effects the data on my device though, right?
But what about the service provider's servers? I guess Whatsapp/ iMessenger/... DO keep copies of my messages on their servers in encrypted form. But what about Signal?
Signal only keeps a copy of encrypted messages while they are in transit. Once delivered, they are deleted immediately from their servers.
> The option you showed on Signal that makes messages disappear after a set amount of time only effects the data on my device though, right?
Disappearing messages deletes messages on all devices of all members of a conversation.
@@sunknudsen Ok, thanks a lot for the clarification!
Its good to send messages using internet. But if we use Signal to send SMS instead of the defapt SMS app, is it any better for privacy??
I switched to Signal and I have a Question "Should I uninstall facebook and it apps from my phone?"
and how to config my android phone for better privacy?
YOUR CHANNEL IS GREAT
I would highly recommend uninstalling Facebook, Messenger and Instagram. Unfortunately, being an iOS user, I know very little about Android.
@@sunknudsen thank you for the advice
@@sunknudsen Uninstall social media and use duckduckgo. Download Tor. Factory reset your phone, don't sign in to play store. Download fdroid, aurora store for gapps and micro g service.
@@wlonsdale1 exactly and if it is possible root and degoogle the phone
When I transferred my messages from iphone to pixel. It transferred the immessages. Are they no longer encrypted?
So it is possible that someone can decipher your messages even on signal ? Even on iPhone? Please reply Sun
Technically it's not exacly correct, that encryption without support for PFS uses the same key to encrypt data over and over again. There are always new keys being generated for each session, but without PFS an attacker, who recorded the encrypted communication, can recreate each session key, if he gains access to e.g. the private key of a server.
In TLS only DHE and ECDHE ciphersuites provide PFS.
Anyone know how to import sms chat history if you first declined to import sms? Now that im comfortable with signal, I'd like to also bring sms in. I can figure out how to switch as SMS default, but the chat history import is nowhere to be found.
ever tried keybase?
Good morning. Okay, I know I’m 2 years late but thank you kindly for being clear with your explanation. Much appreciated. Please don’t use Jesuses name unless you’re calling him. 🙏🏻
Just switched to Signal few days ago.
Why can I not get phone calls to work? I have given permissions, changed battery settings and checked the time. Still doesn't work.
I wish Signal had a dialer app with Pixel 5 dialer features.
Can you make a video on how to use Signal as the default SMS service? I’m confused on how that all works, if it’s secure, how it’s secure, etc... Thanks!
Hey, Signal is only private and secure when one communicates with other Signal users… on Android, Signal can also send regular text messages, but with no additional privacy and security… on iOS Signal is Signal-to-Signal-only (which, I find, is less misleading).
@@sunknudsen I see. Thanks for that clarification! You’re seriously one of the greatest RUclipsrs ever! Thanks for all you do.
How long until Apple integrates this to their iOS software?
we should make a signal group chat =p
I love ❤️ Signal I will never go back to WhatsApp if it’s owned by Facebook it isn’t
Secure
Does a VPN kinda do the encryption too? Or am I wasting money on it?
It really depends on use case and threat model. This is a great question for github.com/sunknudsen/privacy-guides/discussions.
Is that the same as IMEI which you can find by dialling *#06# on your mobile devices?
Althought the IMEI and IMSI are both identifiers, they are not identical. See en.wikipedia.org/wiki/International_Mobile_Equipment_Identity vs en.wikipedia.org/wiki/International_mobile_subscriber_identity. IMEI identifies the device while IMSI identifies the customer.
Can you explain where RCS fits in
Thanks for sharing. Hadn't stumbled upon RCS. Will read up.
I can't wait to try this app with Wifey. Is Signal more secure than Samsung messages?
I believe Signal is the most secure of all.
@@BeardLAD what app are you referring to that's based in Germany?
What do you think about Threema ?
Hey, thanks for sharing. Haven't researched Threema. I like the fact it's Swiss-made, but the project isn't (fully) open source.
@@sunknudsen You probably didn’t see the news about Threema but they are going fully open sourced very soon also Threema developers are working on multi-device feature.
Please check them out .
signal no longer good check up on them they sold out. nice channel btw i subbed
Does the recipient need to have Signal in order for my sent messages to be encrypted?? Or anything I sent encrypted on my end?
8 months late but yes, both people need to be using the app
Isn’t Signal using SMS and a simple pin to verify who I am? Based on what’s mentioned at the beginning about how insecure SMS is: why is a secure platform relying on GSM for identity?
nothings perfect
It's either that or email. There is no safe way at all to connect.
How can I know if someone block me on Signal? If that person did, I can still see the phone number and that person s profile. What is that mean?
Not sure... I haven't explored that aspect of Signal.
Thing is you can't fully replace iMessage with Signal. You can only text people that have Signal and not everyone uses it.
My question would be if I have signal installed and I message people who don't is signal still beneficial to have?
Great question... Signal can only be used to message other Signal users.
Can you make video about the message you signal app saying “safety number has been changed “ ! That means is no longer encrypted!? Why this happened?! My messages to the same person were not delivered week before then I saw this message what that mean? And how we can secured our conversation back again ?
It is still encrypted. But the key has changed. Did they reinstall signal or change phones?
swearing? so 1980s... but the rest of the info is excellent.
Too bad you still need phone numbers on Signal. Why not be able to skip that??
Feel you... have you watched ruclips.net/video/b9aMJZjZ4pw/видео.html
@@sunknudsen Awesome! Thank you. Pleeeeease keep the videos coming! I’ll happily watch an entire 15 second commercial for your content lol.
We now provide mobile numbers for WhatsApp, Signal, and Telegram verification without having to share your personal information.
Facebook deleted
WhatsApp deleted
Signal Downloaded 👍
Hi, Sun. Is it ok if we use our own number? What will happen if we use our own number for Signal? Will our data/privacy be compromised?
Hey Michal, it’s totally fine to use our own number on Signal unless we do not want to be discoverable or have a sensitive use case such as whistleblowing for example.
@@sunknudsen OK thanks you. Just one more question please. There are some sites online that lets us use temporary/disposable numbers. Would signal work if we use these disposable numbers to register? Or does it have to be a number that we will have to use throughout using signal? I am not sure how signal works with registering a number.
Sorry for the late response, RUclips doesn’t notify me when I receive replies to comments. Currently, you need access to that phone number throughout using Signal as it is required to setup Signal on future devices.
Oh! you already know what will comes months ago!
So is it safe to use Signal as 2FA?
I don’t think it is possible actually. Interesting thought though.
If iMessage is end to end encrypted how are you able to also read it on your Mac?
Great question! Using public key cryptography... you could look at the specification for the Signal protocol (not the same but similar concept).
Sun Knudsen so apple would store your private key on their server then?
I haven't researched their implementation, but my gut feeling is they would not store the private key at their end. See security.stackexchange.com/questions/18908/the-inner-workings-of-imessage-security.
That being said, iMessage being proprietary, I would highly recommend using Signal.
@@sunknudsen well I'm on Android so I'm using iMessage anyways I was just curious
I mean,, the biggest question or problem is not if I wanna switch to Signal, it's if other want to do it aswell... See all my family members, friends and colleges use Whatsapp. I can start using Signal but they don't want to use it. Like litterally nobody. They all think whatsapp is fine and is no problem to their privacy or they just don't care if it is.. For me this is the biggest problem. So there are only 2 options. 1 continu using whats app,, or 2 break online contact with basically everyone I know -,-'.
Feel you, but you are not alone... one by one, people are starting to care about privacy. DON'T GIVE UP!
i choose 2.
Tell them to email you then
I had google. Message on my phone samsung galaxy a21 and it was 3rd party app went back to sms
Sir im so much worried about my privacy. Im using signal. But still i get anxiety about is it really secure? Like they don’t have any error right in their encryption? Sir please reply 😭🙏
Hey Sneha, in theory, the cryptography is secure and has been extensively peer reviewed. That said, I haven’t reviewed the code myself, so this assumption is based on trust. Depending on one’s use case, I would also consider attack vectors related to the phone itself... and one should always secure Signal accounts with strong alphanumerical pins.
@@sunknudsen okay thanks sun . But in another video u also said even nsa can’t decipher the chats ? Like it’s secure to use right? For private messaging. See the encryption key is on my phone right. Then how can someone’s can decrypt it without having my device? Please reply 🙏. Thanks
@@sunknudsen hey one last time sun please reply 🙏
What about WhatsApp, I realize it's Facebook owned but it's supposed to be very secure. Love the channel.
Great question... have you watched ruclips.net/video/MxULcUA4B5U/видео.html
Facebook owns it. What else do you need to know?
Sun, is there a reason you are still on Mojave?
thoughts on telegram or WhatsApp?
Great question Ronit. Have you watched ruclips.net/video/MxULcUA4B5U/видео.html
What about ViBER?
Bus i can't see last seen on signal😔
You can
SIGNAL MESSAGING the competitor has no sharing media more than 1 person in 1 click... or forwarding our messages to 50 people takes about 10 minutes of manipulation (YOU NEED AN EXCEL SHEET TO MANAGE WHO GOT YOUR MESSAGE OR STILL NOT)... I don't want to create groups as they do not know each others...
It works now to forward to many
5 now like WhatsApp for a few days :what a crap.. I need for 50 people
@@bluepawn then stick to whatsapp so facebook know everything about you and what you do. They are the second most invasive on web tracking offenders after google.
GSM??? are we on 2020+ or are we in 1990 ?? We have 4G and 5G now.
Hey guys who don't want to reveal phone numbers. you can rent a number to sign up for signal and never reveal your real one...
Let's not forget apple holds the keys. In signal it doesn't matter
its time to say good bye whattup
safer than Telegram and Telegram Secret Chat?
Signal is the gold standard for encrypted messaging.
@@sunknudsen Arent they both end to end encrypted? Can you explain why telegram is less secure? No phone number?
@@macgyver9013 for safety signal is safer than telegram. Idk how but the truth speaks so
We now provide mobile numbers for signal app verification without having to share your personal information.
A Simvacy number acts as your digital identity and protects your personal details and privacy.
Everything is impossible until it has been done. I have both iMessage (which is my favourite) and unfortunately signal for them annoying Android users. WhatsApp are changing their privacy policies which I don’t want my details changed with 3rd parties. I personally think Law Enforcement are more interested in criminals than reading my messages to family, friends and my social life. With Law enforcement I really don’t care what messages they read of mine but I do so care about my cell network provider. If you’re not doing anything wrong you clearly have zero to worry about. If you are doing something wrong then I hope law enforcement come looking for you. I believe in law and order. 👮♀️❤️🙌🏻
Geeez get the fuvk to it.
Kakao app
i have switched to Telegram and never looked back
Wow dude can you keep your hands still.. Wow unreal
I also installed it thinking Signal is safer than Whatsapp. However, I just received scam message from Amazon says send your address to receive iPhone 12 pro. This is absolutely a fake message but don’t know how the hell this happened??
Someone still reading here? Why Apps with phone verification can still read the SMS while Signal is locked with an Passcode?
