"Over the course of this week, we will be updating the login/signup links and flows on the desktop site. This updated method of authentication, more secure and with a modern design, has been in place on Community Central and on mobile web (for all communities) for several months now."

Will there also be API changes to the login process? I recall some staff member indicated changes to the API that would eventually affect bots, although if this supports oauth then it likely won't be a problem.
