Investigating - Starting at 4:08 PM PT on September 26, 2023, our engineers began investigating a problem in which some SendGrid users are unable to properly login using Two Factor Authentication to their respective SendGrid accounts. Only a subset of customers are affected and only those with "Free" pricing packages are included in this group. When affected account users try to login, they will experience an infinite redirection loop when attempting to login using the Two Factor Authentication error. This incident does not impact mail send. We will provide another update in an hour or as soon as more information becomes available.
