Facebook CEO Mark Zuckberg announced at Facebook's F8 Conference Wednesday that the ubiquitous social network will soon allow users to sign into third-party apps anonymously. 

According to The Verge, it will give Facebook users the option to decline revealing personal details when logging in anonymously.

"Some people are scared of pressing this blue button," Zuckerberg said of the "login with Facebook" icon. "If you're using an app that you don't completely trust or you're worried might spam your friends, you're not going to give it a lot of permissions."

Anonymous logins will hide personal information from developers until the user is comfortable with sharing their personal details. 

"Even if you don't want an app to know who you are yet, you still want a streamlined process for signing in," Zuckerberg said.

The anonymous login is a risk-free way to login and try apps, and some anonymous data can be synced across devices so users will not have to repeat the process. 

Zuckerberg said it is a way for Facebook's billion users to "try apps without fear".

The anonymous login is being tested with a few developers, and will be opened to additional app makers in the following months. 

"You can always sign in with your own identity once you're more comfortable with the app," said Zuckerberg. Once a user signs in with their own identity, there will be permissions to help users decide what information each app can access. 

"For example, if someone wants to share their email address with an app, but not their birthday, they can make that choice with a couple taps," Facebook said in a statement.

Facebook will also begin reviewing new apps that allow users to make sure developers are not posting to a user's wall without a user's permission. 

The new permission screens will be introduced in the next couple months.
