WhatsApp is changing its foundations with this massive change in operation

Previously, you needed a phone number to create a WhatsApp account. This could expose your personal information and make you vulnerable to hacking. Now you can use an email address or other methods to sign up.

WhatsApp, the most important instant messaging application for communication, is preparing to take a new step in its evolution. Gone are the days when you had to share your phone number to communicate with someone. The introduction of usernames will be one of the important changes in the history of the application.

This change, which was announced via the latest update to WhatsApp Web, raises many questions. How will this new system work? What will be the advantages and disadvantages? Fortunately, we already have some answers.

How Usernames Work: Simplicity and Confidentiality

The principle is simple: each user will be able to choose a unique username, similar to what is already done on platforms like Telegram or Instagram.

This username will become your primary identifier on the app, allowing others to find and contact you without necessarily knowing your phone number.

Concretely, here's how it works:

• You will choose a unique username when you set up your account.
• This username will be your public ID on WhatsApp.
• Other users will be able to search for and contact you using this username.
• Your phone number will still be associated with your account behind the scenes, but it will no longer be visible by default.

This development represents a giant step forward in terms of confidentiality. No more awkward situations where you have to give your personal number to a business contact, or vice versa. Your username will act as a shield, allowing you to control who has access to your personal information.

Privacy and Security Implications

Adding usernames to WhatsApp goes beyond a cosmetic change. It has profound implications for privacy and security:

• Protection from harassment: If an unwanted user is blocked, they will no longer be able to access your phone number, limiting the potential for harassment outside the app.
• Privacy in groups: Joining a WhatsApp group no longer automatically means sharing your phone number with all members. A big improvement for those using the app in a professional setting or for large groups.
• Increased control over one's online identity: Users will have the option to create a WhatsApp identity separate from their phone number, providing an additional layer of separation between their digital and real lives.

However, this new feature also raises some questions. How will WhatsApp handle identity theft attempts? What options are available to verify a contact’s identity without accessing their phone number? These points remain to be clarified.

Want your username? We still have to wait. At the moment, this is not possible yet.
