Hi, 

In my experience, yubikeys are not very secure. I know of someone in my team who would generate a few hundred tokens 
during a meeting and save the output in a text file. Then they'd have a small python script which was triggered by a 
hotkey on my macbook to push "keyboard" input. They did this because the org they were working for would make you use 
yubikey auth for pretty much everything, including updating a simple internal Jira ticket. 

Thanks, 

Sabri

Might be something I was doing wrong...

Software-based TOTP offer more security than no one-time passwords, but
admittedly less than the physical tokens. Google Authenticator, Authy,
1Password, LastPass all support TOTP.

I dont know where are people about supporting VPN and one-time passwords on
tokens.

At my work place a few people dont have tokens (OTP - One Time PAsswords). The
reserve of these tokens has been exhausted. NEw ones are being on order. Until
then some people cant get on VPN.

Some people forgot their token on their desk and had to to travel to office to
get it, a thing not good to do to go to office now.

Some (not sure) might have issues with syncing these devices. An OTP token has a
certain skew about clock, and a battery that lasts long. Hopefully, one's token
has been synchronised recently and the battery is new. The length of time one
cant go to office might be anywhere between 21 days (announced) and 2 months
(experrience eg in Wuhan still closed). Some times the synching of clock can be
performed remotely, and some 'coin' batteries can be replaced by the person
with skill and tools, could be extracted from a quartz watch for example.

An OTP device can be of many kinds. Some people keep OTPs on paper (I did some
time ago). Some OTP devices are like Japanese 'tamaguchi' format, others like a
credit card format.

I think most anyone on this list could be considered exempt.
I do hope the same will be true should our respective local and national
governments take similar action.

Yes, a number of "essential services" have been identified as needing to
continue to operate under special dispensation during the lockdown, and
telecoms falls within that.
The details of the implementation of the dispensation may be nuanced.
Experience will tell us more in the coming days.
Mark.
