Website Verification Service

The concepts and technologies disclosed herein are directed to a website verification service. A system can receive, from a web server that hosts a website, a query for a set of authentication credentials (“credentials”) to be used to verify that the website is trustworthy. The system can generate and provide the credentials to the web server. The web server can, in turn, provide the credentials to a web browser device for presentation to a user via a web browser application executing on the web browser device. The system also can provide the credentials to a verifier device. The verifier device can present the credentials to the user via a verifier application executing on the verifier device. The user can compare the credentials presented via the web browser application to the credentials presented via the verifier application executing on the verifier device to determine whether the website can be trusted.
