I applied for add Mrs. Majuki as an authorized user on my card for an upcoming China trip. (I had actually applied back 3 years ago, but her authorized user card never got added.) Her card appears with the standard red, blue, and green UnionPay logo, not the holographic gold style logo that's on my card. The chip design has changed slightly as well. On the back, the hologram has changed and the standard contactless logo replaced the QuickPass logo.
When activating the card, the authorized user selects a new 6-digit PIN. I've not had another real chip-and-PIN card with an authorized user before, so the only authorized user Visa/MC cards she's had have shared the cash advance PIN. The last 5 digits of the card number are different, and she doesn't have an online account. We will do a test purchase and report back.
My card is on the top and Mrs. Majuki's is on the bottom:
