-                Buzz uses an identity key instead of a traditional account. It’s
-                created on your device and represents you whenever you use Buzz.
+                Your Nostr identity has two parts: a private key that signs you
+                in and a public key you can safely share. You can find your
+                public identity anytime in Buzz Settings.
               </p>
               <p>
-                Your identity belongs to you, not Buzz. There’s no password to
-                reset, and Buzz can’t recover your key if you lose it. Keep a
-                backup somewhere safe and never share it. Anyone with your key
-                can act as you.

-                If you’re new to Buzz, create a new identity key. If you already

+                Your identity belongs to you, not Buzz, and can move with you to
+                another device or compatible Nostr app. Because only you control
+                the private key, Buzz can’t reset or recover it. Keep a backup
