Generating Authy passwords on other authenticators

---

There is an increasing count of applications which use Authy for two-factor authentication. However many users who aren't using Authy, have their own authenticator setup up already and do not wish to use two applications for generating passwords.

Since I use 1Password for all of my password storing/generating needs, I was looking for a solution to use Authy passwords on that. I couldn't find any completely working solutions, however I stumbled upon a gist by Brian Hartvigsen. His post had a neat code with it to generate QR codes (beware, through Google) for you to use on your favorite authenticator.

His method is to extract the secret keys using Authy's Google Chrome app via Developer Tools. If this was not possible, I guess people would be reverse engineering the Android app or something like that. But when I tried that code, nothing appeared on the screen. My gues

a symptom

I am the Japanese and not good at writng English. I'm sorry to my language ability for you.
I sometimes get the following error when logging out of Xorg. It's a little different to [xf86-video-intel] flip_done timed out, but it's similar.
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] ERROR [CRTC:37:pipe A] flip_done timed out.

Using the video=SVIDEO-1:d kernel parameter doesn't work for me.
I'm running Arch Linux (4.17.2-1) on my laptop ThinkPad X220 with xf86-video-intel (my CPU is an i5-2540M).

This describes a basic Arch Linux installation on a Chromebook Pixel 2015.

Note: I'm a coward, so I installed Arch to an SD card instead of wiping out the existing SSD.

Requirements

• SD card. A very minimal Arch installation with XFCE will need about 2GB, so I think 4GB is the minimum you can get by with.
• Arch installer on a USB drive. The 2013.05.01 is broken with the recent netctl change. So either get an older or newer one.
• Some Arch Linux familiarity.
• Time, patience, and good eyesight.
