Thanks for the issue, but I can not remember what this FIXME is for.

Could you please describe in detail what your issue is about?

Case
A login, A logout, B login, B will get some cache info of A (the same token)

So I think we should clear cache in wechaty-puppet when it stopped

OK, I understand, that's the case.

Instead of clear all local cache, I have another solution: save the cache with the token prefix so that the data can be separated from each other (user/tokens), and also when users login after logout with the same token, they can benifites from the cash.

Please feel free to let me know if you have any suggestions, thank you very much.
