A trello board user signed in from a different computer and received a message saying this is a new location (Unusual login attempts on your Atlassian account) - and then they were prompted to change their password. They did. They are now back on their home computer and they received the same message. They were asked to update their password. They did and now it won't allow them to stay on Trello for more than 30 seconds without the error message appearing. I believe this is a bug of some sort, but not sure what the solution is. They've tried resetting their password several times now.
