Apple officially joins the Fast Identity Online Alliance (FIDO), an open association whose mission is to develop and promote stronger authentication standards and help reduce excessive password dependence.
Apple is joining other FIDO members, such as Amazon, Facebook, Microsoft, PayPal, and Samsung, to support the U2F authentication standard.
The Universal 2nd Factor (U2F) is an open standard that strengthens and simplifies two-factor authentication (2FA) using USB or NFC devices based on security technologies similar to chip cards. U2F security keys can be used as an additional two-step verification method in online services that support the U2F protocol, such as Google, Dropbox, and Facebook.
Chrome, Firefox, Edge and Opera browsers natively support U2F. With iOS 13.3, Safari also supports FIDO2-compliant security keys such as the YubiKey with a Lightning port.
The FIDO Alliance was founded in 2013 by a group also formed by Lenovo and Paypal to address the lack of interoperability between secure authentication systems.
