You can now onboard your friends to Hive within seconds using Keychain mobile Apps.

That's a nice feature added.

An account creation ticket will be used if available, or the HIVE price of an account creation (currently 3.000 HIVE) otherwise

I have lot of account creation tickets, so is one of them going to be used ?

And can I do all these in browser extension ? or I need to download the app ? I see the browser extension that I am using does not update on its own ?
