Dolos is a Chrome extension developed by Charles Quirin that simplifies the process of generating unique alternate email addresses from your Gmail Address. By entering your Google email address in the extension's options page, you gain access to a drop-down menu item. This feature allows you to effortlessly create and copy new custom email addresses to your clipboard directly from any web page.

Ideal for developers or admins requiring multiple separate accounts for testing purposes, Dolos appends a timestamp following a "+" to your Google email address, ensuring each generated email address is distinct. These custom email addresses maintain the capability to reach your inbox, making it a convenient tool for managing various web app accounts seamlessly.
