The use came after Facebook introduced a number of new features for its mobile apps.
This includes the imminent introduction of even more adverts into Messenger, which will soon start carrying adverts from businesses within the app itself, giving advertisers even more ways to target users of the social network.
However the Facebook app will also be more secure thanks to the introduction of tougher security measures.
The social network has made its service compatible with third-party security keys like FIDO U2F – a small thumb drive-esque USB accessory that enables two-factor authentication.
Keys, like those manufactured by Yubico, plug into the USB port and generate a one-off code to input alongside your username and password.
Users will also see that the icon for Facebook Messenger, which has over a billion users worldwide, has changed in order to show uniformity across the company’s apps.
