Best Secure and Encrypted Messaging Apps in 2026

Your text messages and calls can be intercepted by hackers, corporations, and government entities, putting your private information at risk. Corporations may use your messages for targeted advertising or sell your data, while hackers may exploit it for identity theft or fraud. Governments may monitor communications under the guise of national security. Secure messaging apps are essential to protect your communications, as many default options expose sensitive information through metadata or lack proper security. Signal is recognized as the most secure messaging app, offering end-to-end encryption, being open-source, and free of charge, though it requires a phone number for registration. Threema allows complete anonymity without data collection but has no free version. Telegram, while popular, has security concerns as not all communications are end-to-end encrypted by default. WhatsApp and Keybase are discouraged due to ownership issues affecting privacy. Characteristics to look for in a secure messaging app include end-to-end encryption, third-party testing, open-source code, self-destructing messages, and minimal user data collection.

Facebook designed an app for teens called Bell but never launched it, court records reveal

In 2018, Facebook proposed an app named Bell aimed at high school students to create a safe space for communication about school events and social interactions. Internal documents indicated that Facebook intended for Bell to engage teens and transition them to the main platform after graduation. The app was designed to include features like group chats, event organization, and an anonymous confessions section. Facebook aimed for Bell to reach 80% of U.S. high schools by the end of 2020, with plans to expand globally. However, the app was never developed, and a spokesperson described it as an early exploratory idea dependent on strong content moderation. Meta has faced legal challenges regarding the impact of its platforms on minors' mental health and has implemented features in its Teen Accounts to empower parental control.

Is Microsoft really spying on you with Windows telemetry?

Windows 10 was released in 2015 and faced criticism for its telemetry feature, which some viewed as a surveillance tool. In 2017, the Dutch Data Protection Authority found Microsoft's telemetry settings non-compliant with local privacy laws, leading to changes by Microsoft. Telemetry, termed diagnostic data by Microsoft, is essential for device reliability and security, with a baseline level of data collection set to "Required." Users can opt to limit data collection to this level. The Optional category of diagnostic data may include device settings and browsing history, raising privacy concerns. Microsoft introduced the Diagnostic Data Viewer in 2018 to enhance transparency, allowing users to inspect the telemetry data sent to them. As of now, Microsoft has over a billion monthly active Windows 11 users.

Replicate spatial data using AWS DMS and Amazon RDS for PostgreSQL

The process of migrating spatial data from self-managed PostgreSQL, Amazon RDS for PostgreSQL, or Amazon Aurora PostgreSQL-Compatible Edition to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition using AWS Database Migration Service (AWS DMS) is outlined. Spatial data includes points, lines, polygons, and collections of these features, which are essential for applications like mapping and asset tracking. AWS DMS treats spatial columns as large objects (LOBs) and requires proper configuration for LOB handling and PostGIS support to avoid migration failures. PostGIS is an extension for PostgreSQL that manages geospatial data types and functions, enabling operations such as radius searches and distance calculations. Amazon RDS for PostgreSQL fully integrates with PostGIS, making it suitable for geospatial applications. The migration solution involves ensuring compatibility of PostGIS versions between source and target databases, configuring AWS DMS, and validating the migration. Prerequisites include having an AWS account, RDS instances for source and target, a DMS replication instance, and the PostGIS extension installed on both databases. Tables must have primary or unique key constraints, and geometry columns must be nullable for LOB handling. Best practices for configuring PostGIS include validating version compatibility, monitoring resource usage, and establishing backup strategies. Implementation steps involve creating a spatial table in the source database, preparing the target database, configuring the AWS DMS task with specific settings, and monitoring the migration process through CloudWatch logs. Common errors during replication may relate to LOB handling or PostGIS data types. Post-migration validation includes comparing row counts, verifying geometry data types, and ensuring the functionality of PostGIS spatial functions. Finally, it is recommended to clean up all resources post-migration to avoid ongoing charges.

How Your Android Apps Keep Talking — Even When You’re Not Using Them

When connecting to public Wi-Fi, using a VPN is essential as it encrypts traffic and creates a secure tunnel between the device and a remote server, keeping activities concealed from the local network. Android devices continuously communicate in the background, performing tasks such as updating emails and syncing notes, which increases data visibility on public networks. Public Wi-Fi has become common due to remote work and shared spaces, leading to increased privacy risks as smartphones now store sensitive information like banking apps and personal photos. Users are encouraged to adopt simple security habits, including using a VPN when connecting to public networks. Android devices are always connected, making network-level protection important to safeguard background communications.

New York Sues Valve Over Loot Boxes, Calls Them Illegal Gambling

New York Attorney General Letitia James has filed a lawsuit against Valve, the creator of Steam, regarding loot boxes in games like Counter-Strike 2, Dota 2, and Team Fortress 2, claiming they promote gambling behaviors among youth. The state seeks to stop Valve's use of loot boxes and impose financial penalties. The lawsuit argues that loot boxes resemble traditional slot machines and that items obtained can be traded for real-world value, with a virtual gun skin from Counter-Strike 2 reportedly selling for over a million dollars in 2024. The lawsuit claims Valve intentionally makes high-value items rare to increase their perceived worth and highlights the potential for addiction and illegal gambling, particularly among young people. Valve has not yet responded to the lawsuit.

Windows 11 25H2: When Release Preview suddenly plays beta

Users of Windows 11 25H2 in the Release Preview channel experienced an unexpected transition to the Beta channel after installing Build 26200.7921, as the Release Preview option disappeared from the selection menu due to a server configuration issue. This change forced Windows Update to download version 26220.7872 without user consent. The distinction between the channels is significant, with Release Preview operating within the 26200 band and Beta in the 26220 band. On February 25, 2026, Microsoft restored the Release Preview channel, allowing users to revert to it through a manual update. The Insider Program has evolved into a complex system involving build bands, server-side feature gates, telemetry evaluation, and dynamic channel assignment, which can lead to misconfigurations. Best practices for participants include regularly checking for updates, managing automatic installations, and maintaining recovery snapshots.

Exit Windows S Mode Easily

Windows S Mode is a restricted version of Windows designed for entry-level devices, allowing only apps from the Microsoft Store to enhance security and performance. Users may find it limiting if they need software not available in the Store, such as gaming platforms or professional tools. Exiting S Mode is done through the Microsoft Store by searching for "Switch out of S Mode," clicking "Get" or "Install," confirming the switch, and waiting for the process to complete. This change is permanent, and users cannot revert back without a full reset or reinstallation of Windows. Important considerations before switching include ensuring a stable internet connection, checking the Windows edition, backing up data, and understanding the security risks involved. Common issues during the process include the missing option to switch and installation failures, which can often be resolved by restarting the PC or checking the internet connection. After leaving S Mode, users can install applications from outside the Microsoft Store but must be cautious about security.
