PUNE: The Union health ministry has removed the captcha code option before bookings on Co-Win, a central government official told TOI on Friday.
The government has also limited the number of slot searches per user on the portal, which is likely to prevent bots or browser extensions from automatically and continuously searching for slots.
“Captcha was originally introduced to deter distributed denial-of-service (DDoS) attacks, but it was proving to be an inconvenience for those booking slots. With technology advancing, simple captchas can be tampered with and the introduction of more complex captchas would have proved inconvenient to users,” the official said.
