# Biometric Unlock You can unlock the PolkaGate extension using Touch ID / fingerprint. To enable it, go to **Settings** → **Extension Settings** and turn on the Biometric Unlock toggle, as shown below.

When you turn the option on, a popup will appear asking you to enter your extension password. After entering your password, click the **Enable Biometrics** button in the popup.

Next, you’ll be asked to choose where to save your passkey, such as Google **Password Manager** or **iCloud** **Keychain**, depending on your operating system and browser. Choose one option, then follow the prompt to place your finger on your computer or laptop’s **Touch ID / fingerprint sensor**.

Once you place your finger on the Touch ID sensor, your passkey will be securely saved in the option you selected. If everything goes well, you’ll see a success message, and setup is complete. From then on, whenever the PolkaGate extension is locked — either automatically or manually by clicking the lock icon — you’ll see the unlock screen asking you to use Touch ID. You can unlock without entering your password, while still having the option to use your password whenever you prefer.
