Short lived Tokens for Swift SDK
Hi, I've seen a few posts on short-lived tokens but wanted to be totally clear upon how they work. On my app settings page, I have Access Token Expiration set to 'Short Lived'. When I click o...
1. Short-lived access tokens, such as retrieved by authorizeFromControllerV2, do expire after four hours. The authorizeFromControllerV2 method actually requests "offline" access though, so it receives a refresh token in addition to the short-lived access token.
2. If you use authorizeFromControllerV2 as documented, the SDK will automatically perform the refresh process for you. It will get a new short-lived access token when needed; you don't need to implement anything for that yourself.
3. While the short-lived access tokens themselves do expire, you are correct that, when implemented as above, no further user interaction is required (unless the access is explicitly disabled in some way, such as via unlinkClients) since the SDK will automatically perform a refresh when needed.

Many thanks for the clarification!
