Google Messages update finally adds an important safety tool – and teases a feature I’m surprised the app doesn’t have already

Google Messages is introducing two new features: live location sharing and Sensitive Content Warnings. The live location sharing feature allows users to share their real-time whereabouts, improving coordination for meet-ups. Sensitive Content Warnings aim to protect users, especially minors, from harmful content by notifying them when nude images are sent or received. This feature is automatically enabled for users under 18 and can be managed through the Family Link app for supervised accounts. Users can adjust settings in Google Messages to manage these warnings, which utilize on-device AI to ensure privacy.

Google Messages now finally shields you from surprise nudes

Google Messages is introducing smart alerts that automatically blur explicit images before they are viewed by the recipient. This feature is opt-in for adults, while it is enabled by default for teens. Users will receive warnings about potentially explicit images and can choose to view the image, block the sender, or check the reason for the flag. If users send a sensitive image, the app will prompt them with a caution. All processing occurs on the user's device to protect privacy, and the feature currently applies only to still images, not videos.

Signal vs. WhatsApp — what’s the difference between these messaging apps?

Signal and WhatsApp both offer end-to-end encryption but differ significantly in ownership and data practices. WhatsApp is owned by Meta, which collects metadata about user interactions, while Signal is a nonprofit that collects minimal metadata and prioritizes user privacy. WhatsApp has a more user-friendly interface with features like chat history backups, group video calls, and business tools, whereas Signal focuses on privacy with features like "Sealed Sender" to hide sender identity and options to blur faces in photos. Users prioritizing privacy may prefer Signal, but practicality depends on their contacts' app usage. Users can choose to use both apps for different types of communication.

Signal controversy: Why the secure messaging app is all over the news

Signal is an end-to-end encrypted messaging application that distinguishes itself from competitors like Messenger and WhatsApp through its open-source technology and the use of the Signal protocol for encryption. It encrypts messages before they leave the sender's device, ensuring that only the intended recipient can read them. However, its security is tied to the user's device, and vulnerabilities such as weak passwords and unprotected devices can compromise message integrity. Despite its strong encryption, Signal may not meet the stringent security protocols required for sensitive government communications, particularly due to its message deletion feature and the lack of support for record-keeping. The app is considered secure for everyday users, but may not be suitable for high-stakes governmental communication. The rise in cyber threats underscores the need for secure communication channels, leading organizations to consider encrypted messaging solutions like Signal, while also evaluating alternatives within the encrypted messaging landscape.

Ahead of Signal leak, Pentagon warned of app’s weaknesses

The Pentagon has issued a warning about the security of the messaging application Signal, advising against its use for any communications, including unclassified ones, due to concerns over hacking vulnerabilities following a significant leak.

Signal, Telegram and WhatsApp are not built the same

Jeffrey Goldberg, editor-in-chief of The Atlantic, was inadvertently added to a Signal group chat with high-ranking White House officials, highlighting the complexities of secure messaging applications. Signal is known for its robust end-to-end encryption and open-source nature, which allows for independent security audits. WhatsApp, owned by Meta, also uses end-to-end encryption but raises privacy concerns due to its corporate ties. Telegram offers cloud-based messaging with optional end-to-end encryption for "Secret Chats," but its standard chats lack the same level of security as Signal or WhatsApp. The incident underscores the importance of understanding the security features and vulnerabilities of different messaging platforms.

Which is the most secure messaging app? Expert weighs in after U.S. war plan leak blunder

A significant intelligence breach occurred when Jeffrey Goldberg, editor-in-chief of The Atlantic, was inadvertently added to a sensitive Signal group chat that included discussions about U.S. military operations targeting Houthi rebels in Yemen, involving Vice President JD Vance and Defense Secretary Pete Hegseth. Senate Democratic Leader Chuck Schumer described it as "one of the most stunning breaches of military intelligence." Experts emphasized that the breach resulted from human error, not flaws in encryption technology. Signal is considered the gold standard for secure messaging due to its end-to-end encryption and lack of metadata collection. Other platforms like iMessage and WhatsApp have varying levels of security, with iMessage requiring both parties to use Apple devices for full protection, and WhatsApp collecting metadata. Telegram does not enable end-to-end encryption by default for standard messages. The incident highlights that even the most secure messaging applications cannot prevent breaches caused by human oversight.

What is Signal, the messaging app Trump team used to share war plans?

Top officials from the Trump administration mistakenly included journalist Jeffrey Goldberg in an encrypted chat on the Signal messaging app, discussing military strategies against Yemen's Houthi rebel group. This incident has led to calls from Democratic and some Republican lawmakers for a congressional investigation into a potential security breach. Goldberg reported being added to the chat on March 13, which aimed to coordinate U.S. military responses to Houthi attacks on shipping in the Red Sea. The inclusion of an outsider in the chat raises concerns about the protocols for sharing classified information on commercial messaging platforms. Under U.S. law, mishandling classified information can result in criminal charges, although it is unclear if any laws were violated in this case. Signal is known for its secure messaging capabilities, utilizing end-to-end encryption, and does not track or store user data beyond basic account information. The app has gained popularity among privacy advocates, journalists, and government organizations.

What to know about Signal, the app used by Trump officials to text war plans

An encrypted messaging app named Signal has been used by high-ranking officials from the Trump administration, including Defense Secretary Pete Hegseth and Vice President JD Vance, to discuss a sensitive military operation. This conversation included Jeffrey Goldberg, editor-in-chief of The Atlantic, who reported on the incident. The National Security Council confirmed the authenticity of the messages. Signal, which has around 70 million users, offers end-to-end encryption and is operated by the nonprofit Signal Foundation. Despite its security features, experts warn that it is not immune to hacking, as highlighted by a National Security Agency bulletin in February 2025 regarding vulnerabilities within the app. Government officials have used Signal for sensitive communications, but there are potential legal implications for sharing classified information on nonsecure platforms, which could violate the Espionage Act. Some messages in a group chat were set to disappear after one to four weeks, raising concerns about federal record preservation laws.
