Sendgrid API and Two Factor Authentication

I use google compute engine and use SendGrid to handle email. Exim configuration has worked for ages, then I noticed I could not send emails. For a day I was confused (it happens), then I realized SendGrid is pushing Two Factor Authentication (which I did) so this part of my exim configuration (below) was no longer working. Sure enough when I turned off 2 factor, I could send emails again. begin authenticators sendgrid_login: driver = plaintext public_name = LOGIN client_send = : YourSendGridUsername : YourSendGridPassword So being a good admin, I created a Sendgrid API Key. The problem I am having is there are no clear instructions in terms of how to use exim4 and the SendGrid API Key. I tried creating an environment variable for the key (using export), then using: client_send = : YourSendGridUsername : MY_SENDGRID_ENV_VARIABLE But that didnt work. So I tried client_send = : YourSendGridUsername : TheActualKeyItself That didnt work. When I go to the mail queue, and try to deliver the mail, I can see that authentication is failing. What am I missing?

  Some additional trial and error, finally got this one. If this is wrong please let me know, but it does work. sendgrid_login: driver = plaintext public_name = LOGIN client_send = : apikey : TheActualKeyItself What's interesting is I found a post elsewhere that said substitute your userID for apikey (which is what I tried), I also tried using the ApiKeyID, which didnt work either. Just simply "apikey" as the user did the trick. The only question I do have is around security of this approach. I also noticed "export" was not permanent as an environmental variable - which I found is normal after much reading.

  Hello,

  Some additional trial and error, finally got this one. If this is wrong please let me know, but it does work. sendgrid_login: driver = plaintext public_name = LOGIN client_send = : apikey : TheActualKeyItself

  
  I'm glad you were able to get this working. We suggest the same configuration here:
