Hi @test_2023,
I can confirm that the mail is official and not a phishing email. We are in the process of dispatching your AWS credits and you should receive your coupon codes for that shortly. (Round 2 of the challenge will also go live soon!)
As for the Passport requirement, tagging @ashivani who can clarify it.
Though, this is good feedback for us to explain the document requirements in a better way, and not be considered phishing mail.
