So why can you not login to Heroku now?
Other than the obvious question of, are you sure you are using the correct password? Are you sure? Okay, I believe you because Heroku wants ALL users to reset their passwords.
So what do you need to do?
Click on the forgotten password link on the login page and reset it. This will tighten security for all heroku accounts. Also I believe they are rolling out Multi factor authentication for all accounts too.
This is great for security and reduces the likelihood of the security incident to happen again.
Thank you for listening. If this has helped you, please like this post or comment below.
