# PassKey

PassKey revolutionizes how you secure your account by replacing traditional passwords with your device's biometric authentication.

Instead of manually typing a Payment Password, you can authorize transactions and logins instantly using Face ID, Touch ID, or your device’s PIN. It’s not just faster, it’s phishing-resistant, as your biological key can’t be stolen as a password can.
