asp.net - How can I define the clientID (or other data) in a bearer / access token using OWIN -

i trying figure out how put clientid (or additional data might need) inside bearer/access token.

i using owin oauth create tokens. can add claims identity ticket ecnrypted/serialized token , passed client.

the client calls protected api , api de-serializes token , sets iprinciple user. identity object contains username, , scopes in claimsidentity.

i additional information, such clientid made request token in first place.

i can put data inside claim; works hack.

i've done quite bit of searching , not sure how, if possible, store additional data inside bearer/access token.

thanks in advance!

you can store in authenticationproperties object code below:

            var props = new authenticationproperties(new dictionary<string, string>             {                 {                      "as:client_id", (context.clientid == null) ? string.empty : context.clientid                 },                 {                      "username", context.username                 }             });          var ticket = new authenticationticket(identity, props); 

and read need unprotect token code below read properties ticket. id din't find direct way create token without passing token, know not ultimate answer might help.

 string token = "token goes here";  microsoft.owin.security.authenticationticket ticket = startup.oauthbeareroptions.accesstokenformat.unprotect(token);
