Browsers know too much about us. Our frequently used browsers record our bookmarks, history and passwords etc. Many people want to know how to lock browser with password to make sure of our privacy. Common browsers are Google Chrome, Safari, Edge, and Mozilla Firefox etc. None of them have built-in password protection. Fortunately, our computers and phones have built-in app locker tool can be used to lock browser apps. Also I’ll recommend several reliable third-party applications in this article.
