Heroku login - There was a problem with your login

Question

I am trying to login into my heroku account but that fails with There was a problem with your login. I have already reset my password and tried logging in from four different browsers on three different machines, to no avail.

I would raise a ticket at the heroku helpdesk but that is not possible without login. Any idea how to proceed on this? I haven't found a traditional hotline to call either...

Answer 1

Heroku experienced a major security incident last month and further determined that an "attack agent" exfiltrated hashed passwords. Because of this incident, Heroku reset all user passwords on May 4.

From the incident page:

Salesforce is ensuring all Heroku user passwords are reset and potentially affected credentials are refreshed. We have rotated internal Heroku credentials and put additional detections in place.

For now, a password reset to something other than your last password is not a bad idea.
