This string isn't accurate for the RSSI check proximity.

It's not accurate from a technical perspective, but it's the messaging we agreed
on for showing the user, because it seems likely to make intuitive sense to a
user.  Let me know if you feel strongly about this; and if so, we can discuss
further with Marco and Michal.

I don't particularly have strong feelings about this, as the user should almost
never see this message.

         When your phone is unlocked and nearby, just click to enter. Otherwise, you’ll see a locked icon and need to type your password.
