Enable OAuth2 for Thunderbird, No More (probably) Gmail “Less Secure Authentication”

The Thunderbird/Gmail Dilemma

I have been using Mozilla Thunderbird fooooorreeeevvvvveeeerrrr because it is the same interface on all operating systems and has been a nice, consistent system to use.  And it works great in the tray in Linux. 🙂

For about as long as I have been using Thunderbird I have been using it to manage my GMail account and also since them GMail has not allowed Thunderbird to connect with anything but the old fashioned “Less Secure Authentication”.  Well, I just spent 5 minutes looking it up and now that is no longer a problem!  Now you don’t have to gimp the security of your Google account for the sake of simplicity:

Step 1: Turn off “Less Secure Authentication” in GMail

Unless you need this for other apps, then don’t.  If you don’t know what I am talking about and you know you have setup your own external access (through your phone, for example) then this step is unneccessary.

Go to your account settings in Google.  Under Connected apps and sites unset “Allow less secure apps”, so that it says “Allow less secure apps: OFF”.

Step 2: Turn on OAuth2 on all GMail accounts

Follow this link for specific details, no need to re-invent the wheel.

Voila!

And there we go, high quality security for your Thunderbird.
