Notices by Signal (signalapp@mastodon.world)

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. https://signal.org/blog/pdfs/germany-chat-control.pdf

In 2023, Signal was the first mainstream messenger to enable post-quantum cryptography. We’re still ahead of the (elliptical) curve, implementing a new hybrid PQ ratchet ensuring Forward Secrecy & Post-Compromise Security even in a post-quantum world. https://signal.org/blog/spqr/

A reminder that Signal will never reach out to you proactively, never send you a Signal message, and never ask for your verification code. The only way to correspond with Signal is via email (support@signal.org) or the Signal Support Center (support.signal.org).

Until now, if you lost or broke your phone, your Signal message history was gone, a real challenge for everyone whose most important conversations happen in Signal. So, with careful design & development, we’re rolling out opt-in secure backups.

Secure backups will let you save an archive of your Signal messages remotely in privacy-preserving form, refreshed daily.

Now available in the latest Android beta release, rolling out to iOS & Desktop soon

We're ready for Microsoft Recall and the automatic screenshots it takes of everything on your desktop.

Signal Desktop on Windows now includes support for a new "Screen security" feature designed to block screenshots of your Signal chats.

Now on Signal Desktop: A brand-new selection interface that makes it easy to find an emoji, sticker, or animated GIF that’s perfect for the moment. Happy chatting!

Signal is open source, so our code is regularly scrutinized in addition to regular formal audits. We also constantly monitor security@signal.org for any new reports, and we act on them with quickness while also working to protect the people who rely on us from outside threats like phishing with warnings and safeguards.

This is why Signal remains the gold standard for private, secure communications. 5/

Phishing isn’t new, and it’s not a flaw in our encryption or any of Signal’s underlying technology. Phishing attacks are a constant threat for popular apps and websites. 3/

In order to help protect people from falling victim to sophisticated phishing attacks, Signal introduced new user flows and in-app warnings. This work has been completed for some time and is unrelated to any current events. If you’re interested in learning more, this WIRED article from February 19th (over a month ago) goes into more detail:

One piece of misinfo we need to address is the claim that there are ‘vulnerabilities’ in Signal. This isn’t accurate. Reporting on a Pentagon advisory memo appears to be at the heart of the misunderstanding: https://npr.org/2025/03/25/nx-s1-5339801/pentagon-email-signal-vulnerability. The memo used the term ‘vulnerability’ in relation to Signal—but it had nothing to do with Signal’s core tech. It was warning against phishing scams targeting Signal users. 2/

Right now there are a lot of new eyes on Signal, and not all of them are familiar with secure messaging and its nuances. Which means there’s misinfo flying around that might drive people away from Signal and private communications. 1/

Sometimes one way to say "thank you" just isn't enough, so merci, danke *and* bedankt 🇧🇪

"We have ceded so many of the core operations of our lives and institutions to tech, we must recognise that strong encryption isn’t the enemy of security — it *is* security." - Signal President

Our position remains clear. We will not back down on providing private, safe communications. We join with other encrypted messengers pushing back on the UK's flawed Online Safety Bill.

It's always an honor to Finnish in first place. Kiitos, 🇫🇮!

Coming soon: When you add a linked device (Desktop or iPad), bring your whole chat history + last 45 days of media. The transfer process is end-to-end encrypted & completely optional.

Don't want to leave the past behind? We leave you to your own devices.
