"This browser or app may not be secure" error when trying to sign in with Google on desktop apps
The problem must lie with the particular account because I can log into the same app just fine with other Google accounts. The problematic account otherwise works well (e.g. logging in on the web, using it for Chrome Sync, accessing Gmail). In case this matters: it is the only account where I use Two Factor Authentification.This browser or app may not be secure. Learn moreTry using a different browser.

The first is an update to Chrome version 79. Uninstalling chrome, and reinstalling it may solve some peoples issues.
The other issue is allowing third-party services to connect to your Google account. If enabling 'less secure apps' does not solve the issue, then I can only suggest you seek support directly from the app developer.

It is still possible to log in to OneDrive from a real browser, but the internal browser used by the application OneDrive on Windows 10 does not seem to be allowed by Google anymore (while it worked perfectly fine before December).
We did not change any security setting of the GSuite domain.
Furthermore, the use of an App password (which seems to be a secure alternative to allowing less secure app) does not solve the issue.

win.loadURL(`/url/path`, { userAgent: 'Chrome' });As you are a gsuite user, if you are the domain admin, contact gsuite support regarding this. If you are not the admin, then request your admin contact Gsuite support.
