Help with someone's mail
If someone has asked you to help watch their email, they'll read you a six-digit code from their own Kyoka app. Enter it here.
Codes last fifteen minutes and work once. After you enter it, the person you're helping still has to approve you by name in their own app — so nobody gets access just by knowing a number. They can take that access away at any time, on their own, and everything you do is recorded in their activity log under your name.
