1. No more SMS and TOTP. FIDO2 tokens only.
2. No more unencrypted network traffic - including DNS, which is such a recent development and they're mandating it. Incredible.
3. Context aware authorization. So not just "can this user access this?" but attestation about device state! That's extremely cutting edge - almost no one does that today.
My hope is that this makes things more accessible. We do all of this today at my company, except where we can't - for example, a lot of our vendors don't offer FIDO2 2FA or webauthn, so we're stuck with TOTP.
Banks and media corporations are doing it today by requiring a vendor-sanctioned Android build/firmware image, attested and allowlisted by Google's SafetyNet (https://developers.google.com/android/reference/com/google/a...), and it will only get worse from here.
Remote attestation really is killing practical software freedom.
Detecting changes — and enforcing escalation in that case — can be enough, e.g. "You always uses Safari on macOS to connect to this restricted service, but now you are using Edge on Windows? Weird. Let's send an email to a relevant person / ask for a MFA confirmation or whatever."
You just described the usage pattern of a pilot with a family, a truck driver, a seaman, etc.
It’s only unusual if your definition of usual is “relatively rich, computer power user”.
I travelled a lot for work, and never had issues with account access. Nor did my wife ever have issues related to accounts. We don't share Google accounts though. It sounds like that user has personal accounts being used by three people for business use... Which isn't "A seaman and his family".
