"This app is blocked"

[goldbergyoni]

When trying to login first via workflow:login, Google OAuth screen is shown, when I choose my Google account the following message appears:

"This app is blocked. This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access."

I allowed less-secured apps in gsuite configurtion.

Any idea why?

I too have this problem, Google Says I need to use an app password.
