Facebook announced that it had discovered a security breach affecting 1.4 million users.
Facebook CEO Mark Zuckerberg acknowledged the “significant” issue and said it was “very, very important” to update users’ settings to make sure they were safe.
Facebook also said it would help users fix the issue in the coming days.
“We’re working hard to get everyone up and running, but we also need to fix this as soon as possible.
This is an important security issue,” Zuckerberg wrote in a Facebook post.
“In the coming weeks, we will provide a set of steps users can take to update their settings.”
Users can go to Settings > General > Update Facebook to view the update.
“Please be sure to follow these steps: Change your password to one that is stronger than your old one,” Zuckerberg said.
“If you’ve not changed your password, enter a new one.
If you’ve changed your old password, re-enter it.
If your new password is weaker than your current password, try again.”
He also urged users to change their passwords frequently.
“This is a serious issue, and it’s something we’re working very hard to fix as soon the issue is fixed,” Zuckerberg added.
Facebook said that users who are affected will have access to updates from the next few weeks.
“The vast majority of affected users have already received the update,” Zuckerberg stated.
“But, if you’re a few hundred of the affected users, you’ll see that you may have been unable to update because your email address is not valid.”
Zuckerberg did not say how long the fix will take.
He said that “there are likely some problems with the data protection policies” on Facebook’s servers, but that it was unclear what those issues were.
“I’d like to reassure you that we will continue to work with you to get the data back to you as soon and securely as possible,” he said.
Zuckerberg also reiterated that the company does not store users’ personal information, despite what people might assume.
“Our data protection practices are based on strict security practices and we have strong data security controls in place.
If someone were to try and access your data, it would be treated as an unauthorized access,” he wrote.
“So if you are one of those people, you need to be aware that your data is safe and secure.”
Zuckerberg added that “Facebook is committed to protecting users’ data.”
The post follows a similar statement by Facebook CEO Mike Schroepfer on Monday, which said that a “small number” of people had been affected by the breach.
The company said it notified users on Tuesday, and added that it would give them an opportunity to change the password they were using.
“There are likely issues with the information protection policies of Facebook servers.
We are working with our partners to address those issues and will share any further updates as they become available,” Schroepffer said in a statement.
“With these fixes in place, we expect to have some of our current customers up and working shortly.”
