Logging into your BNP Paribas account online relies on three elements: a client ID, a secret code, and, in most cases, validation from a smartphone via the Digital Key. This last step, often missing from standard guides, is crucial for successfully logging in on both computer and mobile.
BNP Paribas Digital Key: the lock that guides forget
The majority of tutorials still describe BNP Paribas login as a simple username/password pair. In practice, the bank has made the Digital Key the cornerstone of strong authentication. Each login to the client area, each sensitive operation (transfer, adding a beneficiary) triggers a push notification on the registered smartphone.

This mechanism replaces the old confirmation SMS. Validation is done directly in the BNP Paribas My Accounts app, either by entering a personal code or through biometric fingerprint.
One technical point deserves attention: the Digital Key is linked to only one smartphone at a time. Changing phones requires a reactivation procedure. The bank then sends a code via SMS to the mobile number registered in the client file before the new device can be associated. Without prior updating of the phone number with the bank, reactivation becomes complicated and may require a visit to the branch.

Client number and secret code BNP Paribas: where to find them
The client number is a ten-digit identifier assigned at account opening. It appears on several documents: the welcome letter sent by the bank, paper account statements, or the contract signed at the branch. In the mobile app, it appears in the “My Profile” section.
The secret code is a six-digit password. Upon first login, a temporary code is sent by separate postal mail from the one containing the identifier. This temporary code must be changed at the first use.
Forgotten password or locked account
After several incorrect entries of the secret code, access is automatically locked. There are two options to unlock the situation:
- From the mabanque.bnpparibas website, click on “Forgot secret code” and follow the reset procedure, which involves sending a new temporary code by mail or validating via the Digital Key if it is active.
- Contact customer service by phone to request a reissue of the codes, with identity verification.
- Visit a branch with an ID to obtain immediate unlocking and the creation of a new secret code.
Resetting by mail usually takes a few business days. The Digital Key, when functioning, allows for a quicker return to normal.
Private Banking space and My Accounts app: two distinct accesses
A common trap concerns BNP Paribas Private Banking clients. Their online space is separate from the public space. The login URL is not mabanque.bnpparibas but mabanqueprivee.bnpparibas. Attempting to log in on the standard portal with Private Banking credentials generates an error message, with no clear explanation of the cause.
The My Accounts mobile app aggregates both environments. A Private Banking client can view their accounts there, but some wealth management features remain accessible only via the dedicated web portal.
Login on computer or mobile
On a computer, the login goes through the mabanque.bnpparibas site. The input field displays a virtual keyboard for the secret code, designed to limit the risk of capture by malicious software. The numbers change position with each display.
On smartphone, the BNP Paribas My Accounts app (available on Android and iOS) combines login and Digital Key validation in one tool. Fingerprint or facial recognition replaces code entry if the biometric feature is activated in the app settings.
BNP Paribas connection security: reflexes to check
The bank never asks for the secret code to be communicated by phone, email, or SMS. Any solicitation of this type is phishing. The official site exclusively uses the bnpparibas domain (mabanque.bnpparibas, mabanqueprivee.bnpparibas). A URL that deviates from this, even slightly, indicates a fraud attempt.
Some checks reduce the risk:
- Access the site by typing the address directly into the browser’s address bar, never via a link received by email.
- Check for the presence of the HTTPS lock before entering your credentials.
- Always log out after each session, especially on a shared computer.
- Keep the mobile app updated to benefit from the latest security patches.
The connection to the BNP Paribas account online relies on a balance between ease of access and successive layers of security. The transition to the Digital Key has added a step, but it protects against nearly all classic impersonation attempts. Keeping your phone number updated with the bank remains the most underestimated gesture to avoid being locked out at the wrong time.
