Random Authentication Sign Outs in ASP.NET Core 2.1 about identity HOT 4 CLOSED

I do have a custom implementation of the UserStore and RoleStore, but I don't know where to begin in debugging this.

I've finally worked out what this is. It's to do with cookie validation checking being run every 30 mins by default. It's a fault in asp.net core 2.1 and should be fixed in 2.2.
See this thread for further details.

The interval at which is runs is configurable. Is your problem that when it checks it will always lock you out? If that is the case are you implementing a security stamp?

You remove the validator altogether by removing the event in the cookie options.

We're closing this issue as the behaviour discussed seems to be by design.
