"The circle of trust"
Please.
Please.
Implying that this interpretation may/should be true for others comes across to me as self-serving, though. You can attach whatever meaning you wish to a circle, but unless you make an actual effort to convey that meaning, then a circle remains... a circle. And they haven’t made any effort to do so here.
IMO, They’re just serving up a big cup of hyperbole for anyone willing to take a sip. Par for the usual corporate course, I guess.
And how about this gob of drivel in the announcement:
> ... makes it easier to talk about why it's important to feel good about email.
Meanwhile, documentation of essential features has gone stale:
>Keep in mind that U2F is not enabled in Firefox by default. >Good if you want the best security and you're only using Chrome. https://www.fastmail.com/help/account/2fa.html?u=04c140b1
U2F 'security.webauth.u2f' is enabled by default, at least for the 67.0.4 Linux build, current on Ubuntu 16.04.
