Can't connect to Trello for Mac using Google with security key for 2fa

Marcus Kamps

Hi,

I'm attempting to reconnect my Trello for Mac. I selected Sign in with Google and entered my password. My Google account's two-factor authentication is set up to look for my U2F security key. When Google's "Complete sign-in using your security key" prompt comes up in the Trello window, my key does nothing. There is also no option to fall back to an Authenticator code or other method, so I can't log in.

Is there a way to get past this, preferably without changing any of my Google security settings?

 

Edit: If I leave the screen hanging for several minutes, eventually it times out and offers to try another way, such as an Authenticator code. Which is great! But there's no other way to get to this alternative than by waiting a long time (and not too long, or the whole session will expire), so it would be much better to have that option right away.

Yes there is!

I had this problem for a LONG time! 

Check your Chrome extensions - there are loads that don't let Google talk to Trello! I disabled all of mine at once and then turned them back on one by one and refreshed Trello each time to see which one was causing the problem.

Google 'talking' to Trello invovled a cross-site tracker, so any trackers or ad blockers and things like that, don't like it.

Go through each of them until you find the one that's stopping them from 'speaking' and then on that specific extension make sure to 'whitelist' both Trello and Google. Then carry on going through the rest of the extensions, because it's a distinct possibility that it's not just one that's blocking them.

For example, I have Privacy Badger, uBlock Origin, Stands, and a number of others that block cross-site tracking, which is exactly what we want Trello to do!

Hope this helps
