I'm aware that Flarum remembers your login for 2 weeks AND that you are able to log out however I do feel that it is a useful security feature to have and users are used to it. For me I don't remember paswsords on my mobile device and I don't always remember to logout so this is a useful compromise.
I would have imagined this would be part of the core but as it's not been implemented, and I'm guessing by comments I've read not going to be, that's all good so was wondering if it could be done as an extension?
PS I've also searched for this and can't see other requests, if I've missed it then my apologies.
