Support for U2F security keys
I have long debated getting a Yubikey but have held off because I don't want to have to carry around several dongles at all times to be able to send an email.<p>Surely other people are in the situation of:<p>- iPhone, iPad<p>- Macbook with only USB-C ports<p>- Windows/Linux workstation with only USB-A ports<p>Is there currently a non-cumbersome solution that will work on all of these?
