How to set up two-factor authentication (2FA)

Two-factor authentication (2FA) is a security layer that requires you to enter a one-time code generated by Google Authenticator in addition to your password when signing in to your Paribu account. You can set up 2FA on both the Paribu app and the web.

How is two-factor authentication (2FA) set up?

To set up two-factor authentication (2FA) on Paribu, verify with your password on the Security settings page, add the Paribu setup key to Google Authenticator on your phone, and complete setup by entering the 6-digit verification code. Once 2FA is active, the Google Authenticator code is requested when you sign in and during security-sensitive actions.

Before you start

• Download the Google Authenticator app on your phone
• Make sure you know your Paribu account password

Enable 2FA on Paribu

1. Open Paribu.com and hover over the profile icon at the top right
2. Click Security settings in the menu that appears
3. In the Security steps section, click 2-factor authentication
4. In the Set up Google Authenticator window that opens, read the information and click the Continue button
5. Enter your password and click the Continue button

Add it to your authenticator app

6. Open the Google Authenticator app on your phone and tap the (+) icon
7. Scan the QR code shown on the screen with your phone or enter the setup key manually

Complete the setup

8. Click the Continue button
9. Enter the 6-digit code from Google Authenticator and complete the verification

Note: When setup starts, a confirmation code is also sent to your registered phone number. The description on the setup screen shows which number it was sent to.

What changes after two-factor authentication is set up?

Once 2FA is active, the following actions request the Google Authenticator code instead of an SMS:

• Signing in to Paribu
• Confirming a crypto asset withdrawal
• Verification before changing your password
• Changes to security settings

How is your security level affected?

The Security level indicator at the top of the Security settings page looks at two steps on the web: 2-factor authentication and passkey. If neither is complete, the level is Critical; if one is complete, it is Medium; if both are complete, it is Secure. When you only set up 2FA, your level becomes Medium; once you also create a passkey, it rises to Secure and the Secure account label appears on the page.

Note: This indicator is not related to account verification (KYC). Even if your account is verified, the level may appear as Critical if you have not completed the security steps.

Two-factor authentication (2FA) is a security layer that lets you enter a one-time code generated by the Google Authenticator app, in addition to your password, for operations that require a security step. You set it up on the Security settings screen.

How to set up two-factor authentication (2FA)

To set up two-factor authentication on Paribu, tap Two-factor authentication on the Security settings screen, enter your password and the verification code sent to your phone, add the Paribu setup key shown on the screen to the Google Authenticator app, and complete the setup by entering the 6-digit code the app generates.

Before you start

• The Google Authenticator app needs to be installed on your phone — the Explore Google Authenticator button on the setup screen opens Google's own setup page
• You need to know your Paribu password
• You need access to your registered phone number — a verification code is sent to that number during setup

Set up 2FA

1. Tap the menu icon in the top left of the screen to open the Account section
2. Tap Account and settings
3. Tap Security settings
4. Under Security steps, tap Two-factor authentication
5. On the Set up two-factor authentication screen, tap Continue
6. On the Enter your password screen, type your Paribu password into the Your password field and continue
7. Enter the verification code sent to your registered phone number
8. On the Set up your Paribu key screen, tap Copy key — if you would rather not enter the key by hand, you can open the Setup key QR code screen with Show QR code
9. Open the Google Authenticator app, tap the + icon and enter the setup key or scan the QR code
10. Return to the Paribu app and tap Continue
11. On the Two-step verification screen, enter the 6-digit code generated by Google Authenticator — if you copied the code in the app, you can enter it with a single tap using Paste code
12. Tap Complete setup

When the setup is complete you return to the Security settings screen and the switch on the Two-factor authentication row appears on.

Warning: Before continuing, make sure you have successfully added the Paribu account in Google Authenticator. If you tap Continue before the key is added, you will not be able to generate the code required in the next step.

What changes after 2FA is set up?

After two-factor authentication is enabled, the Google Authenticator code is requested instead of SMS verification for operations that require a security step. These include:

• Signing in to Paribu
• Changing and resetting your password
• Crypto asset withdrawals — when the transaction requires verification
• Disabling two-factor authentication

Note: Your security level is determined by how many of three steps you have completed: two-factor authentication, a passkey and biometric authentication. If you have completed none of them it shows Critical, one or two of them Medium, and all three Secure. Setting up 2FA raises your level to at least Medium.

If the code you enter is not accepted, the screen shows The verification code you entered is incorrect. If you have trouble setting up or using 2FA, you can check the How to resolve two-factor authentication (2FA) issues article.

Frequently asked questions

Why is two-factor authentication (2FA) necessary?

2FA is an extra security layer that prevents unauthorized access to your account. Even if your password is compromised, operations that require a security step cannot be completed without the code from your authentication app.

Can I scan the QR code instead of entering the setup key by hand?

Yes. With the Show QR code option on the Set up your Paribu key screen you can open the Setup key QR code screen and scan it with the camera in Google Authenticator. Both methods give the same result.

Can I use an authentication app other than Google Authenticator?

Paribu's screens describe Google Authenticator, but the setup key is a standard authentication key. It also works in authentication apps that support the same standard, such as Microsoft Authenticator or Authy — you only need to add the setup key or the QR code to the app you prefer.

I changed my phone, how can I access my 2FA codes?

If you were able to move your authentication app to your new phone, the codes keep working. If you were not, you cannot disable 2FA yourself; please contact Paribu Support: 0850 303 60 00

Can I disable 2FA?

Yes, you can turn off two-factor authentication from the Security settings screen. For details, you can check the How to disable two-factor authentication (2FA) article.
