Signal Introduces Usernames for Encrypted Messaging: A Secure Way to Connect

Signal, the encrypted messaging service, is launching a new feature in the coming weeks: support for usernames. This beta feature allows users to establish unique usernames, enabling connections without divulging phone numbers.

To create a username, navigate to your settings and select "Profile." Once you've chosen a unique username, generate a QR code or link to share with others. Recipients can connect by entering your username into the chat bar. Usernames can be changed at any time, though previous usernames may be claimed by others. Signal began testing usernames last fall.

Unlike social media platforms, Signal usernames do not serve as logins or public handles. They offer a discreet means of communication without revealing personal phone numbers. While a phone number is required to register for Signal, sharing it is optional.

Usernames remain private and do not appear on profiles or in chats unless shared explicitly. As Randall Sarafa, Signal's chief product officer, explains, "Signal does not provide a searchable directory of usernames."

In addition to usernames, Signal is introducing other security enhancements. Users can now restrict who can initiate chats using their phone numbers. The app will default to hiding phone numbers unless saved in contacts. These features are currently exclusive to the beta version.

While usernames enhance privacy, Signal advises users to verify contacts using safety numbers and displays warnings for potential impersonation. For more information, visit Signal's support page to learn about upcoming features.

Safeguarding Internet Privacy: Supreme Court of Canada Upholds Protection of IP Addresses

In a recent ruling, the Supreme Court of Canada affirmed the significance of privacy rights concerning internet addresses. The court declared that police cannot simply obtain a suspect’s IP address without a court order, emphasizing the expectation of privacy that Canadian residents hold for such information. The court's decision stemmed from a case in 2017 involving Calgary police investigating fraudulent online activities at a liquor store. Initially, police demanded IP addresses from a credit card processor, which eventually led to obtaining subscriber information from Telus. This information was pivotal in making arrests and securing convictions in multiple offenses. Despite previous convictions, the accused contested the legality of obtaining IP addresses without proper authorization. The Supreme Court, in a 5-4 decision, asserted that IP addresses carry a reasonable expectation of privacy, necessitating judicial approval before access. The ruling emphasizes that obtaining jud

Apple approves single letter name for twitter IOS app

In a series of noteworthy updates, Twitter, the popular social media platform, has officially rebranded itself to a single-letter name "X" on the App Store, marking a significant change in its visual identity. This move came after weeks of alterations to its social media handles, interface branding, and even web redirects, generating quite a buzz among its users and followers. Interestingly, Apple usually maintains a policy against allowing developers to name their apps with just a single character. However, it seems that Twitter's parent company, X Corp., led by the renowned entrepreneur Elon Musk, managed to secure an exception from Apple, granting them the unique opportunity to use "X" as the app's name. This exception was particularly significant, as the App Store Connect portal typically displays an error when developers attempt to use a single character as the app's name. In conjunction with the name change, Twitter also revamped its App Store tagl
