Your Account Is Locked to Your Email
The email your Hive account gets bound to now appears as a locked line on the create page rather than an editable field, so the account that gets minted is the one you actually asked for. One address means exactly one account: asking again for an email that already has an account will not mint a second one. The one-time keys page now also walks you through Keychain setup, which extension or app to install, how to import, and which key to import (never your owner key). A successful mint hands you alpha access on the spot.
