The company confirmed that it enabled this functionality in India starting July 1.
Meta introduced this ability for merchants to authenticate users in other geographies last year. However, it started allowing these types of messages from organizations in Malaysia in June and India in July.

The company also applied an international authentication rate last month to activities such as sending login codes to cross-border users.
"As we mentioned onstage at 'Conversations' last month, we want to give people and businesses the ability to get more things done right on WhatsApp — and that includes one-time passwords so people can get a login code and quickly sign in," a Meta spokesperson told TechCrunch. 

Everything then becomes easy to give consumers and businesses ways to verify their accounts through their favourite apps, making WhatsApp the best place for business getting done.

Forcing such a key market as India to activate would be a big deal, with estimates suggesting telecom networks send over one billion one-time passwords every single day. For WhatsApp, that counts India to be its largest market with more than 500 million users, it is an opportunity to have some of those authentication messages go through its platform and collect revenue from businesses in the process.

WhatsApp has been overhauling its messaging fees for businesses since last year. Authentication messages provide a new way for WhatsApp to bump up that revenue and habituate users to use the app more. Last month, the company also announced AI-powered features for designing ads to helping merchants with customer support on the WhatsApp Business app.
