This. It is inconvenient, but it does help with the issue that systems constantly get compromised and credentials stolen.

I wish companies would support more user friendly technology like ubikey or similar instead…

Also SMS is extremely insecure, and relatively easy to spoof/steal.

I use a notepad in many meeting at work to not be a complete pain in the ass.

If I write it down it’s not lost, and if it’s actually a good point I can bring it up at a good time or circle back to it.

It is a house rule and its pretty popular.

It potentially adds a layer of strategy where you should/could retain a +2 or +4 as a defensive measure.

Personally i like this house rule as it makes for more surprices in play when you can defend yourself against those cards.

It does make the game potentially longer and more unpredictable, so like all house rules its a matter of taste.
