Just a quick heads up:
I don’t know if this is new or not, but I think it might be.
Throughout my use of ZwiftPower.com over the last two years, it has always wanted me to add numbers to my in game Zwift name to confirm I am whoever I say I am (and if I wasn’t, why would I say I am?).
However, today, it no longer needs this.
In fact, it seems to now be linked via OAuth to Zwift’s servers. Hurrah.
Does this have any impact? Well… no, not that I can see. But it does recognise my account as owning my Zwift profile without temporarily changing my name. Great success.
