I'm using Ory Hydra as OAuth2 server. There's a config to set custom expiration time, but it's static and used for all tokens that I create. https://www.ory.sh/docs/hydra/guides/token-expiration#access-token-expiration
I want to have the ability to set the token's expiration time when I create a token for the client (expiration time per token) or at least when I create the client (so I'll be able to use different expiration time for different clients). Is it possible?
Can you share a bit more on your use case? AFAIK it is not possible to configure the lifetime of tokens per client at the moment. But in most cases I can think of this would not be necessary from a security standpoint, so I am would like to learn more why you are looking to configure the lifetimes individually.
If you have a refresh token the lifetime of an access token is negligible (in most cases) and best to keep reasonably short! In the scenario of web/native apps this definitely applies and you will have more complexity if you have different lifetimes as you will have when just following the refresh token flow.
