PSD2 Bank Synchronization: How to Connect Your Accounts Securely

The PSD2 Directive Explained Simply

The European PSD2 directive (Payment Services Directive 2) obliges banks to open access to your bank data to approved providers, with your explicit consent. This is known as Open Banking.

How the Connection Works

The 3-Step Process

1. You choose your bank in the financial management application
2. You are redirected to your bank to authenticate yourself (username + password + two-factor authentication)
3. You authorize the sharing of your account data (balance and transactions)

What the Application Can See

* Your real-time balance
* Your transaction history
* The details of each transaction (amount, date, description)

What the Application Cannot Do

* Make transfers from your account
* Modify your personal information
* Access your banking credentials

The Security of Your Data

End-to-End Encryption

Data travels via encrypted connections (TLS 1.3). No banking password is stored by the third-party application.

Mandatory Approval

Only providers approved by the ACPR (Autorité de Contrôle Prudentiel et de Résolution) can access your bank data. Always check for this approval before connecting your accounts.

Concrete Benefits

* Global overview: all your accounts (checking, savings, credit) on a single screen
* Automatic categorization: every expense is automatically categorized
* Real-time alerts: be notified when your balance falls below a threshold
