It's a genuine question to see what number span people are using to
remember random numbers.

For me it depends on the numbers themselves.
Sometimes it easier in pairs or 3-3 or even 4-2 or 2-4
But mostly I don't find I need to remmeber them.

When on-line backing or logging in to MS-teams or outlook, they send a sms
and that goes to iMessage and that opens up asking to you want to use this code
and it's sorted.
