Uncertainty and change! The same reason people panic buy bog roll and fuel![]()
Give over... I'm Asperger's/Autistic, and if I can deal with it without batting an eye, nobody else has any excuse.

Yep, very annoying and honestly I don’t get why it’s required. I’m a big boy and I can decide what accounts I give enough of a crap about to use strong passwords and 2FA on. A computer forum is not something I care enough about to bother so forcing me is just annoying especially as I use it on 3 devices. At least set the timeout to forever or a long period of time.
You may or may not 'give a crap' about your account, but I'm sure OcUK and the Admins/Dons do - from both a liability PoV and a 'keeping our community safe from noobs with compromised accounts' PoV. You should have strong passwords/phrases and MFA enabled everywhere, not just on some sites. Otherwise, what's the point? You only need to be compromised on one or two weak places and it soon dominoes.
