I’ve had two factor for gmail enabled for two years.  This morning, I set up two factor for github and some others due to Heartbleed (check if sites you use are affected), Then there was Twitter.  After the other sites being straightforward, I expected the same from Twitter.  Twitter did not deliver.  I had to turn off two factor.  I’m left with secure my password and hope I notice if someone logs into my account.  (I think my friends would tell me about bad direct messages)

How to enable on a mobile device

1. Install the official twitter app on my iPad
2. Follow the menus described here
3. Write down the backup code
4. I logged off in a browser and re-logged in.
5. Then I went to the twitter app and approved my login under settings.

And if it ended here, all would be fine.

Adding a phone number

I thought about adding a phone number as another option.  Don’t bother.  They are mutually exclusive.

Apparently they are mutually exclusive.  I cancelled the phone number sign up process part way through due to usability issues.  (Twitter wants you to text GO to 40404.  I don’t know how to do that on my BlackBerry.  I know how to reply to texts and text real numbers.  And I don’t want to lookup how to do it since I likely never will again.)

Anyway, when I clicked cancel on the process, it had already turned off my iPad option so I had to set it up again.  Grumble.

The BlackBerry app

Once I had two factor turned on, I was no longer able to logon to Twitter using the BlackBerry app.  A quick search online says I’m not the only one with this problem and the BlackBerry app just plain doesn’t support it.  Which means I can’t use two factor for Twitter.
