I click on profile icon at the top right-hand in chromium and enter my user and pass and click on "log in" button but the frame disappears and I'm not logged in yet, what should I do?
As of 15th of March 2021, Google removed several features from all third-party Chromium-based browsers (also Chromium itself) including synchronization. Users need to either install and use Google Chrome or use alternatives (other web browsers/extensions that provide such a service).
During a recent audit, we discovered that some third-party Chromium based browsers were able to integrate Google features, such as Chrome sync and Click to Call, that are only intended for Google’s use. This meant that a small fraction of users could sign into their Google Account and store their personal Chrome sync data, such as bookmarks, not just with Google Chrome, but also with some third-party Chromium based browsers. We are limiting access to our private Chrome APIs starting on March 15, 2021.
For users who accessed Google features (like Chrome sync) through a third-party Chromium based browser, their data will continue to be available in their Google Account, and data that they have stored locally will continue to be available locally. As always, users can view and manage their data on the My Google Activity page. They can also download their data from the Google Takeout page, and/or delete it here.
Guidance for vendors of third-party Chromium based products is available on the Chromium wiki.
"Chrome Sync API" requires API keys.
Just to extend @L_K answer: after creating API key according to http://www.chromium.org/developers/how-tos/api-keys, you will need to add enviroment variables in any way, for example:
For Windows users run this commands in
setx GOOGLE_API_KEY your_key_goes_here
setx GOOGLE_DEFAULT_CLIENT_ID your_client_id_goes_here
setx GOOGLE_DEFAULT_CLIENT_SECRET your_client_secret_goes_here
For Mac OS X / Linux: Plop these in your
