Here are the details:

In the letter, the Ministry of Information and Technology said it had taken note of ​WhatsApp’s announcement that it would introduce usernames, allowing users to ⁠initiate conversations without revealing their phone numbers.

“We’ve announced the option for ​people to reserve their preferred username on WhatsApp,” a Meta spokesperson said, ​adding that the feature is not yet live and that the company has reserved usernames for public figures, government entities and verified Meta accounts to help prevent ​impersonation.

The IT ministry said the feature could materially increase online fraud, ​phishing, digital arrest scams and impersonation attacks by allowing bad actors to contact victims ‌without disclosing their phone numbers.

It also expressed concern that usernames resembling those of individuals, financial institutions or government agencies could facilitate identity spoofing and impersonation.

The move comes days after Reuters reported that India had scrutinised Telegram ​over anonymity features ​that allow users ⁠to interact without revealing phone numbers.

In June, a home ministry report reviewed by Reuters said such privacy ​features make identity detection difficult and raised concerns over ​the app’s ⁠use in cyber fraud and the sharing of illegal content

Telegram also lost a legal challenge last month against India’s temporary ban on the messaging platform, ⁠after ​the government argued in court that features ​including username-based interactions and concealed phone numbers created enforcement challenges.
