Hi, 

In response to a data breach at 23andMe, Ancestry have implemented two-step verification.

I've set this up in the manner I am accustomed to, send me a verification code via email.

But I've just read the instructions and I was confused by what I saw.... 

If you sign in with Apple or Google, no Ancestry verification code is needed. Link your account with Apple or Google, or follow the steps below to turn on two-step verification.

How does an Apple or Google login make you as secure as 2SV?
