How can they tie onchain and wallet activity together?

When people received their first Aptos Airdrop, peopel logged in to their site with their email and oasswords, before joining this platform too, you had to either register a new user or login your previously created user.

So I believe the same method will be used for the second drop!

By the way, Airdrop is confirmed.
