I have been looking into using mongoDb fully for my service and saw the authentication part of Realm which looked neat. Then I started to dig into this and found out that none of the SDKs seems to support the use of the refresh token that you get once you login? There doesn't seem to be any API where you can validate if a token is valid any more? The refresh token lifetime seems to be 30 mins which doesn't work at all in a mobile concept since you wanna keep the user logged in between the uses of the app you need to be able to refresh the access token when you login which won't be possible if the refresh token is only alive for 30 mins.

Is there any plans on improving this so this can be used in a real example? And what is the timeplan in that case so I know if I will be able to use this for my scenario or not.
