I logged into Keychat using Amber. In the 'Me' tab, I noticed a 'Create ID' option. When I clicked it, I found an already generated seed phrase, and several npubs derived from it were already listed there. I don't recall ever setting up a seed phrase myself. Was it automatically generated either when I logged into Keychat through Amber or upon my very first access to Keychat?
Also, this seed phrase is completely separate and in no way linked to my Amber key, right? This is because my Amber private key wouldn't actually be stored in Keychat, correct? Is my understanding accurate?
Regarding usability, while for typical Android Nostr apps it's convenient to just use the native app directly and log in using Amber, I find that for web clients (or PWAs), viewing them through Keychat is more convenient.
