Google blocked the app when Gmail is used

This problem was present for older versions of the Cal App that was using Google account to send the certificates by email. This option is not used in version 108 and higher.

Problem:

I’ve tried to test the manual calibration on the Calibration App and when I set up a Gmail account for the test email it can’t send a test email.

I have checked that the name and password is correct.

I logged into the Gmail account and there was a mail from google that said they have blocked the login due to “an app that is not from Google”.

When I tried to unblock the app so I could login, I came to a page that said, “Google blocked the app you are trying to use because it does not meet our security requirements”.

Solution:

This is Google protection.

You must use an App Password as described here https://support.google.com/accounts/answer/6010255?hl=en#zippy=%2Cuse-an-app-password.

After you set the app password, first confirm the you did it in the mail from Google and then enter it as a password.
