Opera Mini is a mobile-first browser with cloud compression and proxy features. It does have a native desktop or Chrome extension version. Therefore, directly "logging into Opera Mini" inside Chrome is impossible because Opera Mini is a separate application. However, users can log into Opera Cloud Services (account synchronization) via Chrome to access bookmarks, Speed Dial, and data saved from Opera Mini. This report outlines the correct method, limitations, and alternative solutions.
Opera Mini and Google Chrome are two of the most popular web browsers, but they operate on entirely different engines and ecosystems. If you are looking for an "Opera Mini login Chrome" solution, you are likely trying to sync your bookmarks, passwords, and speed dials between these two platforms.
Opera Mini itself doesn't have an official extension for Chrome, but you can use the Opera browser, which offers a sync feature.
