Thanks for your responses!
We didn't go that way because account creation tickets are non-transferable and we wanted to be able to create accounts with that as well. But there is an easy way involving QR Codes in the other direction. Your friend create their account on their mobile device, generate a QR Code and send it to you. You scan it, pay (HIVE or ticket) and their account is created.

Taking some time to think about it, I guess account creation tickets can still be used if I send a friend an invite to join Hive. Whether I pre-pay 3 HIVE for them or I keep an account creation ticket ready, it still has to be verified that my friend is the one registering the account. So my invite would anyways have some secret token in it. Then when my friend wants to create the account, Keychain would know that it is my friend, and either use the 3 HIVE to create the account or redirect the request to me so I can use my account creation token to create the account. If I have account creation tokens, I am a more advanced user so I can run some software that takes the request Keychain redirected to me, creates the account and notifies Keychain it has been created - this way my friend doesn't have to wait, the account is created right away. And RC delegation can be handled similarly.
Of course, there are many ways to go about this and it's also possible for my friend to send me a QR code, then I create their account. But it seems slower and more steps. Better to have it more automated, I guess. And generating an invitation via an Invite a Friend button seems like a standard feature that people are used to.
The format of the master password is determined at account creation time, are you aware of any account creation tool that create accounts with a seed? We could verify it's working when importing accounts and propose it as an option during account creation if feasible.
I see that Ecency has implemented a seed phrase: https://ecency.com/signup/wallet On the second step you are shown a seed that you can download together with all the account keys. hived also has a suggest_brain_key() function where it derives a private key from a list of words, but it uses a different (much more cumbersome) list of words than the BIP39 protocol.
We consciously chose not to store the master password or the owner key for security reasons. Keychain is a hot wallet, not a key storage tool.
Got it.
