First of all thank for taking the time to reply.

Few things happened,

1. I tried to create a new hive account directly from the app with a username that I selected @walterjay.card
2. This prompted me to selected between "use a preferred crypto" and pay $1,99 or "Create with a friend" using an already registered Hive account.
   I selected the second option in order to use my main account to do that, that where a QR code was generated but when I scanned it with my Ipad I got the Error "No usable data found" and the processed stopped there.

(I tried to take a screenshot of the QR code but it was disabled in the app by admin so not possible)

Since I couldn't interact with the QR code (no link or no ability to click or scan it with another device) I went back to the main screen and did the following.

1. register the @walterjay.card account directly on the blockchain using my primary account and got a new set of keys.

2. try to import that newly created account using the "Import and Link" option in zypto app on android.

3. Input in the Zypto app username: walterjay.card

4. Input Keys: I tried both the active key and owner key without success and that where I got the message "Invalid Master Password"

I know the key is the right one because I used the same copy paste to input it in another wallet to login to my new account using Hive keychain.

For the record both keys start with either 5H or 5K not P5. I am talking about the hive keys and not the keys to the zypto wallet.

My question then is how can I import an existing Hive account in zypto?

I am not sure what he means by recovery key on Hive.

For the QR code maybe I can't cross platform it in this case I am not sure how we can use a friend with a hive account to create another account via the zypto app. I was expecting a link in the qr code to sign a transaction onchain with another account but maybe that is not the thinking behind it.

I am really looking forward to testing this new product/bridge so thank you for developing it and I hope it can help both our ecosystems.
