"Sign in with Google temporarily disabled for this app" error when trying to authorize a script

Question

I am trying to run this simple Google Script.

However, it does not allow me to authorise. How can I proceed?

Answer 1

Update 1:

• As reported by Rubén, Google says it won't fix this - #163
• Some workarounds are provided in #76, #145 and #150 - showing solutions like changing GCP and providing a oauth consent screen.

Update:

Switching Google cloud project from default to a standard project have resolved the issue for some users. This is still a workaround and may not work for all. Therefore, star the issue below.

This seems to be a new issue affecting certain users. You can ★(on top left) star the issue here to let Google developers know that you're affected by this issue and to prioritize the issue.

Answer 2

It stopped complaining once I specified the script only needed access to the current sheet. Google explains how to do it here.

All you need to add to your code is this JsDoc annotation:

/**
 * @OnlyCurrentDoc
 */
