Managing online bank accounts is no longer just about checking a balance in your bank’s client area. Since the full implementation of PSD2, user journeys have been restructured around strong customer authentication (SCA), which requires rethinking the choice and arrangement of financial tracking tools.
Strong Authentication and Its Impact on the Usability of Online Banking Tools
PSD2 has made SCA mandatory for accessing accounts and initiating payments. In practice, each connection to an aggregator or third-party application requires a one-time code, biometric validation, or confirmation via the issuing bank’s app.

This mechanism often leads to frequent session interruptions. An aggregator querying four different banks may trigger four distinct validation requests, sometimes spaced just a few hours apart. We observe that this friction drives some users to abandon multi-bank centralization, even though it remains the most effective lever for managing cash flow.
The technical workaround involves connections via regulated APIs (open banking). Aggregators that rely on these APIs maintain longer sessions and reduce the number of re-authentications. Before choosing a tool, ensure it effectively utilizes the PSD2 APIs of your institutions, rather than relying on simple screen scraping, which is more fragile and often interrupted.

Open Banking and Multi-Bank Aggregation: Technical Selection Criteria
Open banking has led to the emergence of aggregators capable of centralizing real-time flows from multiple institutions. Bankin’, Linxo, or the modules integrated into neobanks utilize banking APIs to automatically categorize expenses, generate cash flow forecasts, and trigger alerts.
Not all aggregators are created equal. We recommend evaluating three areas before committing:
- The actual bank coverage: some tools claim theoretical compatibility with several hundred institutions, but the actual connection varies depending on the APIs exposed by each bank. Test the connection with your own accounts before migrating your data.
- The granularity of categorization: a system that classifies a SEPA direct debit as “Miscellaneous” every time adds no analytical value. Favor solutions that allow you to create custom categorization rules and learn from your manual corrections.
- The exportable data model: if the tool does not allow you to export your transactions in CSV or via an outgoing API, you remain captive. Structured data export is a non-negotiable criterion for any serious budget tracking use.
Multi-bank aggregation makes perfect sense for freelancers and small business leaders juggling personal accounts, business accounts, and sometimes a dedicated corporate treasury account. Centralizing these flows in a single interface avoids blind spots on payment deadlines.
Predictive Detection of Financial Incidents by Banking AI
Several retail banks and regional banks are now deploying predictive algorithms to spot weak signals of financial fragility. The goal: to anticipate a recurring overdraft or a payment incident before it occurs.
These systems analyze spending patterns over several months, identify unusual drops in income, and cross-reference this data with the upcoming direct debit schedule. When a risk is detected, the client receives an alert, sometimes accompanied by a proposal for a cash facility or smoothing of direct debits.
The benefit for the user is real, provided they understand the limitations. These models operate on the account history held at the concerned bank. If your cash flow passes through multiple institutions, the algorithm sees only a fraction of your actual situation. This is precisely where multi-bank aggregation complements the system: by consolidating flows, you gain a perspective that the bank alone cannot construct.
Security of Account Management Tools: Beyond the Password
Security no longer relies solely on the username/password pair. Biometric authentication (fingerprint, facial recognition) has become the standard for accessing mobile banking applications. For third-party tools, the trust chain relies on the regulatory status of the provider.
An aggregator licensed as an Account Information Service Provider (AISP) under PSD2 operates under prudential supervision. It only has read-only access to transaction data and cannot initiate payments or store your banking credentials in plain text.
Concrete points of vigilance:
- Check that the provider is listed in the financial agents register of the ACPR or an equivalent authority in the European Economic Area.
- Always enable two-factor authentication on each connected service, including budgeting tools that do not directly handle funds.
- Be wary of applications that ask for your direct banking credentials instead of going through the authentication flow redirected to your bank. Sharing credentials outside the PSD2 flow exposes you to phishing.
Cash Flow Tracking for Freelancers and Small Businesses: Specifics to Know
Consumer-grade account management tools poorly cover the needs of independents and small businesses. The separation between personal and professional flows, tracking collected VAT, reconciling bank statements with issued invoices: these functions require tailored solutions.
Financial management software oriented towards businesses (like a banking module integrated into invoicing software) allows for the automation of reconciliation between statement lines and client or supplier invoices. This reconciliation, often manual and time-consuming, becomes almost instantaneous when the tool utilizes real-time transaction data via open banking.
For a freelancer, the main challenge remains visibility on short-term cash flow. Client payment delays create cash flow gaps that traditional predictive alerts do not capture, as they are based on past flows rather than outstanding receivables. Combining bank aggregation with tracking expected receipts remains the most reliable method to avoid unpleasant surprises.
The choice of an online account management tool primarily depends on the complexity of your banking situation. A single account at one bank can be easily managed from the native client area. As soon as you multiply institutions or manage professional flows, aggregation via open banking and automated reconciliation become technical building blocks that are hard to replace with a spreadsheet.
