What is Passkey Login?
Passkey is a secure login method that replaces the traditional username + password. It uses your fingerprint, facial recognition, PIN code, or physical security key to verify your identity.
Core advantages:
No need to enter a password, log in faster;
Supports Face ID, Touch ID, biometrics or device PIN verification;
Anti-phishing attacks, hackers cannot obtain your login information through fake websites;
Login credentials are only saved on your device and cannot be stolen on the server side;
Cross-platform support, Apple, Google, and Microsoft ecosystems are all interoperable.
In other words, even if someone gets your Facebook username, they can't remotely hack it unless they can unlock your phone.
Facebook Passkey Features Detailed Explanation
Functionality coverage:
Supported devices: iOS and Android are fully supported;
Compatible applications: Facebook is the first to be launched, and Messenger will follow later;
Additional uses:
1. Support automatic filling of Meta Pay payment information through Passkey;
2. Can be used to protect encrypted message backups.
Security encryption principle:
Passkey uses public key and private key encryption mechanism:
The private key is stored on your device and never uploaded;
When logging in, the system signs the challenge message with the private key, and the remote server verifies the identity with the public key;
This means that even if the server is compromised, your login credentials cannot be forged.

Why did Facebook introduce Passkey?
Facebook has always been a popular target for hacker attacks, especially since many users have linked their accounts to other services (such as Instagram and Meta Pay). Once stolen, the consequences can be serious.
The introduction of Passkey has the following key purposes:
Prevent remote hacking attacks;
Protect Meta Pay payment information and encrypt backup;
It will soon be expanded to Messenger to improve the security of the overall ecosystem;
Integrate with platforms such as TikTok and LinkedIn to enhance security competitiveness.
Is Passkey suitable for everyone?
if you:
Commonly used Facebook, Messenger and Meta Pay;
Worried about account theft;
Don't want to remember a bunch of passwords anymore;
The device supports Face ID or fingerprint recognition;
Then I strongly recommend turning on Passkey, which will be the mainstream login method in the future.
FAQ
Q1: What to do if there is no Passkey login entrance?
A: It is possible that your device has not yet been updated. It is recommended to try again later or keep the latest version of the App.

Conclusion
After X (formerly Twitter), TikTok, and LinkedIn launched Passkey, Facebook finally joined the "password revolution."
In the near future, we may no longer need to remember a password. In the future, Meta will also promote this feature to Messenger and more ecological services to bring a more unified and secure user experience.
