How to Safely Connect Bank Accounts and Cards to Apps Without Overexposure

The use of convenience features in web applications should always consider security standards in order to avoid exposing users’ privacy. Mobile applications and online platforms are increasingly dependent on direct linking to bank accounts or cards for the purposes of paying, subscribing, budgeting, or gaining financial insights. 

Though the benefits of these links lie in their speed and convenience, these also present potential risks if the linking itself is wider than required or if the levels of security are low. Giving financial access carelessly can raise the risk of fraud or misuse of data.

Financial security is a function of informed decision-making. Understanding how account linkages function, as well as how to control risks, empowers an individual to leverage technology without sacrificing control of their financials or their data.

Understanding What “Connecting an Account” Really Means

In everyday usage, before connecting any bank account or card to any application, it is essential to make oneself aware of the type of access being granted.

“Read” vs “Write” Accessibility — Looking At Data Versus Transferring Funds

Certain applications will request read-only permissions, wherein the application will only have the ability to read the balance or the transactions.Other applications will demand write permissions, where the application will have the ability to transfer, withdraw, or charge the account. The distinction is important because, with read-only permissions, the risk of damage will be limited.

Single Use Verification vs Ongoing Account Linking

Single-use verification verifies ownership of the account but doesn’t provide continued access. The continuous account link, on the other hand, permits the app access or the ability to carry out certain operations on the account on multiple occasions before the account access can be canceled.

Third Party Aggregators & API Connections

In many cases, apps use a third-party data aggregator or API in connecting with financial institutions.Therefore, financial information could end up passing through another service before arriving on the app.

Understanding the mechanics of connections enables users to easily grasp which systems are getting linked, what data is being accessed or shared, and the purpose behind it. Such transparency equips users to anticipate security and compliance risks, check reliability, and decide wisely and confidently whether to give their approval or authorization.
