This article explains what a passkey is and how passkey authentication works on bitcastle.
🔐 What Is Passkey Authentication?
Passkey authentication is a security feature that allows you to sign in using the authentication method already set on your device.
It is also commonly referred to as biometric authentication.
You can use your device’s existing unlock methods, such as:
・Fingerprint authentication
・Face recognition
・Passcode
・PIN
・Pattern lock
This means you can authenticate securely without directly entering your password.
🛡️ Benefits of Using a Passkey
Setting up a passkey is an important security measure to help prevent unauthorized access and misuse of your account.
By using passkey authentication, you can enjoy a safer and more convenient login experience.
Please note that passkey authentication may not be available on some devices or operating systems, depending on their specifications.
🔒 Protection of Personal Data
bitcastle does not store any biometric data, such as facial images or fingerprint information.
All authentication processes are securely handled on your device.
