SMS Challenge on sign-in to Forum this morning

[pgn]

What's the reason for this sequence of transactions needed to sign in to the Forum on laptop earlier, and just now to the web version of My O2 on mobile, @Dave-O2?

SMS lands, after a warning not to share the PIN that is about to arrive...

Something amiss?

The OTP to sign in was back this morning. (Not into My O2....just the forum)

You mentioned earlier it 'was triggered by certain factors'? Not sure what those factors relate to as I did nothing different. (This is on Windows PC using Firefox and home Wifi. ) Very rarely use phone to log into forum.

I am still required to use a OTP on a daily basis @Dave-O2. It is not a problem but I am intrigued as to why ! 👍
