Why are you asked to fill captcha repeatedly when using a VPN service?
There are countless of people who are confused as to what Google Captcha is and why do they encounter it so often when using a VPN. Many are worried that filling the Captcha may compromise their privacy and online anonymity. Before we answer these questions, we need you to understand what Google Captcha really is.
What a Captcha really is?
The word ‘Captcha’ is an abbreviation for ‘Completely Automated Public Turing Test’. Captchas usually consist of a letter or a number sequence that has been distorted or is a little difficult to read. Captcha is basically a test put forward by Google to deduce whether the entity making the search is actually a human or a bot.
These Captchas are not intended to stop users from browsing, but are made to filter out any fake traffic generated on the site by bots, etc. Only humans are smart enough to pass through the Captcha code.
Why Google wants VPN users to fill in Captchas?
When you use VPN without the dedicated IP feature, you’re actually sharing an IP with other VPN users. This means that there may be countless of people searching for something on Google using the same IP address.
When Google sees a lot of searches originating from the same computer, it confuses these people for bots or spammers, and therefore requests you to fill out a Captcha occasionally. Filling out the Captcha verifies that you’re not a bot or a computer program making fake searches.
Does Google Captcha Compromise Online Security?
Your identity isn’t compromised when filling out Google captcha. This is because the IP address which you use is also being used by other users at the exact same time. This makes it very hard and complicated for Google to track you online footprint. Another fact worth mentioning is that, though search engines maintain logs of searches as they always do, it is very difficult for them to identify who made a particular search and from where.
To further improve online security, users can turn on the encryption feature in their VPN. This makes it impossible for any entity to determine your online identity or to monitor your online communications. Your online identity and anonymity shall always remain protected.
