-### Check the Token Version

-There are different UID2 token versions in current use, and later processing steps are a little different depending on whether the token version is v2 or a later version.

-#### Calculating Token Lifetime: Token v2
-
-For token v2, the calculation to make sure that the token lifetime is valid for bidstream use is as follows:
-
-```
-lifetime = token expiry - current time
-```
-
-For v2, we use the token expiry minus the current time to calculate the lifetime. This is because v2 doesn't have a **Token Generated** field, which is present in later versions. All token versions have an **Identity Established** field, but this indicates the time that the original token was generated, before any token refreshes, so it can't be used to calculate whether the token is still valid.

 ## Honor User Opt-Out After Token Decryption
 
-After decrypting the token, you must check the resulting raw UID2 against your opt-out records. If it appears on your opt-out records, you must honor the user's opt-out preference, including by not using the UID2 for bidding.
