Signal, the popular encrypted messaging service, is currently testing a new feature that allows users to add usernames to their accounts. This feature, referred to as “pre-beta” by VP of engineering Jim O’Leary, aims to provide a more private and secure way for users to connect without having to share their phone numbers. In this article, we will explore the benefits and challenges of Signal’s new username feature.

By introducing usernames, Signal allows users to communicate and message each other without the need to share their phone numbers. This significantly enhances privacy and security, as phone numbers can be personally identifiable information. Users can set up their usernames and share them through unique QR codes or links. Additionally, a username can be designated as the primary contact method on Signal, preventing the exposure of a user’s phone number through their profile.

Signal has been working on implementing the username feature for quite some time. Signs of this feature first appeared in 2019, according to the service’s wiki. Signal’s president, Meredith Whittaker, has also openly discussed the company’s plans for usernames. This development aligns with Signal’s commitment to providing a private and secure messaging experience for its users.

While Signal leads the way in implementing usernames, competitor WhatsApp, owned by Meta, is rumored to be working on a similar feature. However, WhatsApp tends to be more secretive about its upcoming developments. The introduction of usernames by both services showcases the importance of providing alternative contact methods that prioritize privacy.

Although usernames bring numerous privacy benefits, they also introduce potential challenges. One concern is the possibility of users impersonating others. This issue must be addressed to ensure a safe and trustworthy environment for Signal users. The development team needs to implement effective mechanisms to mitigate impersonation and user abuse.

For those eager to try the pre-beta username feature, O’Leary’s post states that it is available for testing across Android, Desktop, and iOS. However, installing the test clients may vary in terms of convenience, and users can only communicate with others using the same pre-release software. It is important to note that this feature is primarily intended for testing purposes and may not be suitable for daily use.

Signal’s new username feature presents an exciting advancement in the realm of private messaging. By allowing users to connect without sharing their phone numbers, Signal enhances privacy and security. However, challenges such as user impersonation need to be carefully addressed. As Signal continues to refine and improve this feature, users can look forward to a more versatile and secure messaging experience.
