[UPDATE] GameSpot has obtained a Twitch email that outlines what type of data may have been compromised. It says:

“We are writing to let you know that there may have been unauthorized access to some of your Twitch user account information, including possibly your Twitch username and associated email address, your password (which was cryptographically protected), the last IP address you logged in from, and any of the following if you provided them to us: first and last name, phone number, address, and date of birth.”

Separately, GamesBeat has a Twitch Support email that says “limited” credit card info also may have been compromised for some accounts.

The original story is below

Amazon’s streaming platform Twitch on Monday reported a possible security breach, resetting passwords and stream keys in the process.

“We are writing to let you know that there may have been unauthorized access to some Twitch user account information,” the company said in a statement.

In addition to resetting passwords and stream keys, Twitch has disconnected user accounts from Twitter and YouTube. What this means is the next time you log into Twitch, you’ll be prompted to make a new password.

Anyone who uses the same or a similar password on other sites/services is urged to change those, too. Finally, Twitch said it will reach out directly to affected users with “additional details.”

It is unclear how widespread the possible breach was or what kind of personal data was actually compromised. GameSpot will have more on this story as it becomes available.

Amazon paid nearly $1 billion to buy Twitch last summer, a move some saw as surprising, given the reported interest from YouTube/Google.
