What is the "Passkey Button" Approach?#

The "Passkey Button" approach is a method for integrating passkeys into an existing authentication system. It adds a separate "Continue with Passkey" button alongside existing login methods like passwords or social logins.

User Experience#

• Users select the "Continue with Passkey" button.
• They authenticate using their device's biometric system (e.g., fingerprint or face recognition) or a PIN.
• Users are often encouraged to create a passkey after logging in with their existing credentials.

Benefits#

• Simplicity: Easy to implement without significant changes to the existing login flow.
• User Control: Users can explicitly choose when to use passkeys, maintaining familiarity with current options.

Challenges#

• Lower Passkey Usage: Users may overlook the passkey option, reducing adoption rates.
• Additional Step: Requiring users to make an extra choice can add minor friction to the login process.

Real-World Example#

Australia’s myGov portal utilizes this approach, offering users the option to log in with passkeys via a dedicated button.

This method is best suited for organizations looking to introduce passkeys without disrupting their current authentication system while giving users the flexibility to adopt passkeys at their own pace.
