Polls can now be created in individual chats too. Show a curated list of choices to your indecisive friend or recapture the magic of passing a note to your crush by sending a “Do you like me? Y/N/Maybe” poll.

A response to recent reporting in Germany, in service of clarity and accountability:
First, it’s important to be precise when it comes to critical infrastructure like Signal. Signal was not “hacked” — in that our encryption, infrastructure, and the integrity of the app’s code was not compromised. 1/

While we build robust technical safeguards, user vigilance is ultimately the best defense against phishing. We will continue to work on mitigating these risks via interface design and signposting throughout the app. In the meantime, please stay alert, and never share your SMS verification code or Signal PIN with anyone.

To protect people from such phishing, Signal actively warns users against sharing their SMS code and PIN.
We also want to emphasize that Signal Support will *never* initiate contact via in-app messages, SMS, or social media to ask for your verification code or PIN. If anyone asks for any Signal related code, it is a scam. We make this clear when users receive their SMS code during initial signup.

These attacks, like all phishing, rely on social engineering. Attackers impersonate trusted contacts or services (such as the non-existent “Signal Support Bot”) to trick victims into handing over their login credentials or other information. To help prevent this, remember that your Signal SMS verification code is only ever needed when you are first signing up for the Signal app.

2026-03-09 16:16:08 UTC

We are aware of recent reports regarding targeted phishing attacks that have resulted in account takeovers of some Signal users, including government officials and journalists. We take this very seriously.
To be clear: Signal’s encryption and infrastructure have not been compromised and remain robust. These attacks were executed via sophisticated phishing campaigns, designed to trick users into sharing information – SMS codes and/or Signal PIN – to gain access to users’ accounts.

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.

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/

In order to help protect people from falling victim to sophisticated phishing attacks, Signal introduced new user flows and in-app warnings.

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/

2025-03-25 22:48:17 UTC

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/
