Creating a passkey unlock account

Thanks. That took me to the link to create a test account with a different email address. I was successful in creating a new account with a passkey. When I tried logging in on with Safari on my iPhone (same one that I have the TestFlight version of 1Password installed) I selected to login with the passkey associated to the new email address, it appeared to work, but was asking me to check another device that was already logged into the new account for authentication and I got stuck there.
