+#### Protocol Handler Support
+
+Using NIP26, a new oauth-style protocol handler can allow oauth-style login for nostr apps that do not want to be the primary custodians of identity keys.:
+
+Consider the following link that can be opened as an intent in browser and mobile apps:
+
+```url
+nkey://auth?id=<uuid>&**uri**=x &kinds=1,2,4,5&from=<epoch>&to=<epoch>&**pubkey**=<64-char hex pub key>&reason=descriptive+text&relays=r1,r2...
+```
+
+This can open up an associated app or browser that:
+
+ - On success:
+     - Posts NIP26 delegate info to the requested relays (if any)
+     - Optionally posts delegate info to additional relays (if configured
+     -  POSTs a response to the **URI** containing a delegate key encrypted with the requested pubkey and information about what was approved (if anything)
+     ```js
+     {
+      id:"<request-id>",
+      status:"authorized",
+      key:"<b64 encoded nip44 encrypted with the **pubkey**>",
+      from:<epoch-approved-from-time>
+      to:<epoch-approved-to-time>,
+      kinds: [1,2]
+     } 
+     ```
+ -On rejection, POSTs a "rejection" to the **URI**
+ {
+     id:"<request-id>",
+     status:"denied",
+  }
