Hello,
if you want to store the token then you have to used in memory cache in your application and used that in your application and used.
if that token details are used in front-end side then you have to store that data in localstorage and used in front side.
Thanks.

Better to save your token in local storage in brower as shown   var  tokenObject = getYourTokenObject;  // get token object       // Put the object into storage    localStorage.setItem( 'Token_data' , JSON.stringify(testObject));      // Retrieve the object from storage    var  retrievedObject = localStorage.getItem( 'Token_data' );      console.log( 'retrievedObject: ' , JSON.parse(retrievedObject));   This is normal practise to store token in browser memory and use the object to various purposes.   Regards Rijwan

there is no need to save the Token anywhere , after getting the token in a variable just use it to passin as credential to the  successive requests. Token are just temperory key,  a client (app) gets to access something on server (third party) on user's behalf.
