Is it still viable to use Signal for privacy in 2026? It’s centralized, and has had many suspicious occurrences in the past.(Unopen source server code, careless whisper exploit which is still active as far as I know, and the whole mobile coin situation.)
Thoughts?
if you are super private person or want to be anonymous, maybe you can choose SimpleX.
PRODUCT PITCH: Hey everyone, I have a great idea for a secure / private messaging service.
It’s hosted in the US, subject to its pervasive spying laws including national security letters.
Also I need all your phone numbers.
Also no you can’t host this yourself, I run the only server.
Everyone who uses signal and supports it, is falling for this pitch.
As per usual, the answer is “depends on your threat model”. For a lot of sensitive communications, the centralised design and therefore ability to correlate metadata is a no-go. But if you’re just using it e.g. as a WhatsApp replacement to message your friends, it’s fine. It’s still the most polished and normie-friendly e2ee foss messenger.
IMHO the question depends on :
- who you are (boring, rando, political dissident, journalist, etc)
- who you talk to (family, friends, work, etc)
- what alternatives actually exist
So… sure Signal is not perfect but if you can’t convince your family members to move to DeltaChat it sure beats using WhatsApp, Telegram, etc.
You may want to read Why not Signal?, but I still use it.
Yes. You will find a lot of randos saying no, but the consensus among security professionals and researchers is that it is still the current standard. Not to say that it doesn’t deserve scrutiny or criticism, or that other projects aren’t important to develop.
