Hi,
As a company looking into api gateways, this would much improve our use case for kong.

Is there any progress on this?

I know that on OAuth plugin there is an expiration, but it could be very usefull on other Authentications

An implementation of this has been proposed at #4239. It leverages the native TTL support of our new DAO implementation, which means that TTLs are specified in seconds with this first pass.

I am glad to close this PR now on behalf of @eskerda who fixed it by submitting a PR #4984. It took some four and half years to get this in, but we finally did, ;-). Perhaps it was worth the wait, like all the good stuff. It feels better if it just doesn't come given. Haha... well thanks again @eskerda! Closing this now.

@bungle is this feature documented somewhere? I can see the ttl field present in Kong API response but don't know how to set it.
