Your browsers spell check is collecting your personal information.


Spell check is a feature used by countless people in their everyday typed communication.  It’s accuracy ensures the number of typos in your documents decrease; this allows people to type with ease.  Most people install spell check extensions to make sending emails and writing papers faster.  A new report from Otto-js co-founder and CTO Josh Summit has revealed that spell check extensions might not be safe. This report shows that spell checking features present in both the Google Chrome and Microsoft Edge browsers are leaking sensitive user information. 

Otto-js co-founder and CTO Josh Summit discovered the leakage that occurs specifically when Chrome's Enhanced Spellcheck and Edge's MS Editor are enabled on browsers.  Josh’s discovery came while conducting research on how browsers leak data in general.

According to the blog “Google & Microsoft can get your password via your browser enhanced spellcheck” published on otto-js website, the spell check features sends data to Google and Microsoft that is entered into form fields.  Username, email, date of birth, and Social Security number, were among the information that was sent while using Google Chrome and Microsoft Edge.  Passwords were sent to Google and Microsoft’s third party servers, if 'show password' is enabled, essentially Spell-Jacking your data. Josh Summit is quoted in the blog post “Chrome & Edge Enhanced Spellcheck Features Expose PII, Even Your Password”  

 “While researching for data leaks in different browsers, we found a combination of features that, once enabled, will unnecessarily expose sensitive data to 3rd Parties like Google and Microsoft.  What's concerning is how easy these features are to enable and that most users will enable these features without really realizing what is happening in the background."


It is not known if the data is being stored once it is received or who is managing its security. However, it raises concern among researchers about tech companies having so much access to sensitive information including passwords.  

To lower the risk of having your data sent to Microsoft and Google disable the spell check feature. If you have manually enabled the spell check feature on your browser, you can turn if off by removing the extension. If you have enabled the native spell check feature present on Google Chrome or Microsoft Edge, you can turn it off from the settings.
