Strong authentication in banking has become a major issue for securing accounts and online transactions. Since its gradual implementation in 2021, this measure aims to strengthen the protection of customers against banking fraud. Le Bot Avocat, a banking law firm based in Paris, provides you with insight into this essential mechanism.
What Is Strong Authentication and Why Is It Necessary?
Strong authentication, also known as two-factor authentication, is a security process that requires at least two distinct identification elements to validate an online banking transaction. This method is mandated by the European Payment Services Directive (PSD2), which came into force in 2018 and was fully implemented in May 2021.
The three categories of authentication elements are:
- Something you know (password, secret code)
- Something you possess (phone, bank card, USB key)
- Something you are (biometrics: fingerprint, facial recognition)
The primary objective of this measure is to effectively combat online banking fraud. Indeed, according to figures from the Observatory for the Security of Payment Methods, remote payment fraud accounted for 72% of the total amount of bank card fraud in France in 2020. Strong authentication aims to considerably reduce this risk.
When Does Strong Authentication Apply?
Strong authentication is mandatory in several situations:
- Logging into your online banking portal (at least every 90 or 180 days depending on the bank)
- Online card payments
- Sensitive operations (adding a beneficiary, wire transfers)
However, certain exemptions are possible:
| Type of Transaction | Exemption Possible |
|---|---|
| Payments under 30 euros | Yes |
| Recurring payments (subscriptions) | Yes |
| Trusted beneficiaries | Yes |
| E-merchants with low fraud rates | Yes |
It is important to note that these exemptions are at your bank’s discretion and may vary between institutions. As a professional accustomed to online transactions, you should be particularly vigilant during your banking operations.
What Strong Authentication Solutions Do Banks Offer?
Banks have developed various solutions to meet the requirements of strong authentication. The main methods offered are:
- Mobile banking app with push notifications: This solution allows you to receive a notification on your smartphone to validate a transaction.
- SMS with one-time code: A temporary code is sent to you via SMS to confirm your transaction.
- Dedicated physical device: Some banks offer specific hardware tokens or USB keys to generate authentication codes.
Each bank has developed its own strong authentication solution, often under a specific trade name (for example, Certicode Plus, Securipass, etc.). It is essential to familiarize yourself with the system offered by your banking institution to avoid any disruption during your online operations.
What Are the Impacts and Best Practices for Users?
Strong authentication has significant implications for users of online banking services. Here are some key points to remember:
- Enhanced protection: In the event of fraud without strong authentication, the customer must be fully reimbursed by their bank.
- Vigilance required: Never share your banking codes by phone, email, or SMS, even if the request appears to come from your bank.
- Adapting to new procedures: Familiarize yourself with the authentication methods offered by your bank to avoid any inconvenience during your transactions.
- Electronic wallets also concerned: Strong authentication also applies to services such as PayPal, Apple Pay, etc.
As an informed professional, you should be particularly attentive to these new practices. Le Bot Avocat advises you to regularly check the security settings of your online banking account and to immediately report any suspicious activity to your bank.
Strong authentication in banking represents a major advancement in securing online transactions. Although these new procedures may sometimes seem burdensome, they are essential and unfortunately insufficient to fully protect your assets and personal data. Do not hesitate to consult a banking law expert, such as Le Bot Avocat, for any questions regarding your rights and obligations in this constantly evolving field.
