5 March 2015. A8 sends:
The Yubikey on the video-extracted picture matches the Basic
Standard model, not the Neo in particular. The copper button
has a different logo in the center. See
4 March 2015. Add photo of Snowden wearing the
neck chain in earliest interview.
A7 sends: A6 is incorrect, the YubiKey NEO can do OpenPGP and lots of other
things... U2F, OTP etc.
Re.: the Pink 'Device' that A3 was asking about.
It's a pink notebook, "la
Moleskine." You can
make out staples in the spine and the slightly fanned-out pages on the right
Also, that IS a Yubikey. The dot in the middle of the touchpad identifies
it as the 'Standard' key. It's doesn't 'do' PGP, it is simply used to store
static passwords or to generate one-time passwords (based on the key's serial
number). The beauty of Yubikeys is that to the computer, they look like a
keyboard so don't need any software to run for them to work.
My guess is that Mr. Snowden was using the Yubikey to store a static
password/passphrase or more likely part of a static password (it would be
the "something you have") and Mr. Snowden typing the rest of the password
from memory ("something you know").
2 March 2015. There appears to be a device attached to Snowden's neck
chain, partly hidden by the dongle, perhaps a security device. Snowden is
shown wearing the chain in the first day of the sessions.
What happened to the devices: destroyed, sanitized, stored, copied? Snowden
claims no documents taken to Russia. Barton Gellman later reported on meeting
with Snowden in Moscow:
"He declined to discuss the whereabouts of the files, but he said that he
is confident he did not expose them to Chinese intelligence in Hong Kong.
And he said he did not bring them to Russia. Theres nothing on
it, he said, turning his laptop screen toward his visitor. My
hard drive is completely blank.

Nothing about the removable storage devices nor what devices were used to
exchange files among the parties reporting, handling, archiving.
A tweets: The dongle looks like YubiKey from Youbico running OpenPGP applet
A2 tweets: The chip Snowden inserts, "It's a pendrive with a copy of the
Tails OS sent to Greenwald by Micah Lee. More info
A3 asks what is the flat, pink device under the chain and corkscrew?
A4 notes the lock.
A5 notes the "chips" are SD cards.

Snowden Hong Kong Security Devices
Clip from Citizenfour at 36:05 in Hong Kong shows Snowden's three memory
chips, two USBs and a security dongle.
00:23:52 Snowden wearing neck chain.
Clips from Citizenfour, 36:47 to 38:13, appear to show Glenn Greenwald in
Hong Kong taking a memory chip from a certified mail envelope, giving it
to Snowen who inserts the chip into Greenwald's laptop, then covers head
to decrypt. Curious, the mailing of an encrypted chip of highly classified
data, unless the envelope is reused from another purpose.
