How to enable biometric authentication

June 24, 2026

Biometric authentication is a security feature that lets you sign in to your Paribu account quickly and securely with the security method defined on your device (Face ID, Touch ID, or fingerprint). By enabling biometric authentication, you can access the app without entering your password and raise your account security level.

What does biometric authentication offer?

Biometric authentication adds a physical authentication layer unique to your device, making your account more secure. When you enable biometric authentication, you benefit from the following advantages:

Fast sign-in — You can sign in to Paribu with your face or fingerprint without entering your password
Strong protection — You ensure your account can only be accessed with your physical authentication
Higher security level — When used together with 2FA and a passkey, your account security level rises to Secure

Security level

Your account security on Paribu is evaluated at three levels:

Level	Condition
Critical	No security step is enabled
Medium	One or two of the three steps are enabled
Secure	2FA + passkey + biometric authentication (all three) are enabled

Enabling biometric authentication is one of the steps to raise your account security level to Secure.

How is biometric authentication enabled?

To enable biometric authentication on the Paribu app, go to security settings and turn on the biometric authentication toggle. The feature is activated within a few seconds with the Face ID or fingerprint registered on your device.

Before you start

Face ID, Touch ID, or a fingerprint must be defined on your device

Enable biometric authentication

Tap the menu icon at the top left of the screen to open My account
Tap Account and settings → Security settings
Tap Biometric authentication
Activate biometric authentication

Note: When you first enable biometric authentication, permission is requested for Paribu to use the biometric feature on your device (Face ID, Touch ID, or fingerprint). Grant permission to continue.

How is biometric authentication disabled?

You can disable biometric authentication at any time. To disable it, follow these steps:

Tap the menu icon at the top left of the screen to open My account
Tap Account and settings → Security settings
Tap Biometric authentication
Disable biometric authentication

Warning: When you disable biometric authentication, your account security level may drop from Secure.

Methods supported on iOS and Android

Biometric authentication supports different methods depending on your device's operating system:

Platform	Supported methods
iOS	Face ID, Touch ID
Android	Fingerprint, Face recognition

Note: You can manage your biometric settings from your device's system settings. Paribu automatically uses the method defined on your device.

Frequently asked questions

Is biometric authentication mandatory?

No, biometric authentication is optional. However, to raise your account security level to Secure, you need to enable 2FA, a passkey, and biometric authentication together.

What happens if I do not have a biometric record on my device?

When you try to enable biometric authentication, you are redirected to your device's system settings. First define Face ID or a fingerprint on your device, then return to Paribu and enable biometric authentication.

What is the difference between biometric authentication and a passkey?

Biometric authentication uses your device's biometric feature only when signing in to the Paribu app. A passkey, in addition to signing in, is also used as a verification method for security-sensitive actions such as crypto asset withdrawals and password changes.

What should I do if biometric authentication is not working?

Check from your device's system settings that your biometric record is active. If the issue persists despite Face ID or a fingerprint being defined, try disabling biometric authentication and enabling it again.
