Signal vs WhatsApp: Vilken Messenger håller faktiskt dina chattar privata?

24 juni 2026 · 2 min läst · Kommentarer

Båda apparna säger att de använder end-to-end-kryptering. Men kryptering är bara en del av historien. Här är vad som faktiskt skiljer dem åt.

Vad end-to-end-kryptering faktiskt betyder

• End-to-end encryption means only you and the person you're messaging can read the contents of your messages. Not the app company, not your mobile carrier, not the government — unless they get into your actual phone.
• Both Signal and WhatsApp use end-to-end encryption for message content. On this point, they are equal. The difference is everything else.

Metadataproblemet

• Even if WhatsApp can't read your messages, it can — and does — collect metadata: who you talk to, how often, at what times, your location, your device, your contacts list.
• Meta (WhatsApp's parent company) uses this data to build advertising profiles and shares it across Instagram and Facebook.
• Signal collects almost none of this. The only data Signal holds about you is your phone number and the date you last connected.

Öppen källkod vs. stängd källkod

• Signal's code is open source — anyone can read it, audit it, and verify it does what it claims. Security researchers around the world have done exactly this.
• WhatsApp's code is closed. You have to take Meta's word for it that the encryption is correctly implemented and that no backdoors exist. Given Meta's track record with user data, that's a lot of trust.

Den praktiska nackdelen med Signal

• The only real drawback: your contacts need to have Signal too. You can't send a Signal message to a WhatsApp user.
• Signal has grown significantly — it now has over 100 million users. Many people already have it.
• The practical approach: keep WhatsApp for group chats with family who won't switch, move sensitive conversations to Signal.

Advantage: Signal — med stor marginal, om integritet är viktigt för dig.
