Hey there, I saw that auth0 uses a SID I am just wondering if this is a permanent tag that will not update every few days / every time they log out and back in. If that is not the case are there any alternates? ---

Hey @SavDevv ! The `sid` claim (session ID) is tied to the current authentication and will be updated when a new session is established. ---

Hey! thanks for the reply. Is there a permanent way of me gathering that like a user ID or something of the sort? ---

> [@SavDevv](#): > > Is there a permanent way of me gathering that like a user ID or something of the sort? Re-reading this again - Just to be clear, the `sub` claim is the `user_id` and does not change. This has nothing to do with the authentication session. The `sid` claim provides that, but of course will change when the session changes. ---

Alright, So to get the user\_id id need to grab it off the SID if that’s correct? - I should add im using node.js for this ---

No, the `sub` claim is equivalent to `user_id` - Sorry for the confusion! ---

Sorry for being a pain, When im on application cookies all it shows is appSession when i have attempted to decode it in [https://jwt.io/](https://jwt.io/) i am met with a error saying that its not a valid json object. What am i doing wrong here? ---

[jwt.io](http://jwt.io) will help you decode JWT (json web tokens) access and/or ID tokens, not cookies. The `sub` claim is a standard claim included in a user’s token(s) upon authentication. ---

Oh right, So i just add on the claim say like ```auto const userProfile = req.oidc.user; given_name: userProfile.given_name, family_name: userProfile.family_name, email: userProfile.email, user_id: userProfile.sub ``` ---
