What is online banking? How it works + pros and cons

Online banking is a service that allows people to manage bank accounts online. Using a computer or mobile device, customers can view statements, make transfers, set up bill payments, and make credit applications without visiting a branch.

It’s never been easier to check bank accounts, track spending, and manage payments.

While some banking activities do require people to visit a branch in person, people overwhelmingly prefer to manage their accounts digitally. In fact, 77% of U.S. consumers prefer mobile or online banking, while only 8% prefer to use a bank branch.1

But it’s not right for every situation, and remote access carries several risks for users. Find out more about how online banking works, what people can and can’t do with it, and the pros and cons.

How does online banking work?

Digital banking is a type of account that allows users to perform banking activities remotely through a website or app.

Choose an institution that offers a secure online platform and open a bank account. Then, create an online account and log in through an app or web portal.

While traditional banking at a branch involves the account holder presenting identification or a card, online banking works by providing account access through a username and password. This is convenient, but it carries certain limitations and security risks.

Once a user is logged in, they can manage their accounts and access banking services.

What’s the difference between online banking and mobile banking?

Online banking involves accessing accounts through a website, while mobile banking involves using an app to access and manage bank accounts.

Mobile banking often offers additional features compared to online banking, such as mobile check deposits and PIN or fingerprint login.

What services does online banking offer?

Most online banks offer core functions, including account management, deposits, transfers, and automatic payments. The specific benefits of digital banking may depend on the institution. Online-only banks may have fewer services and protections than traditional banks and credit unions.

The following are common services offered by banks with online account portals:

Manage checking, savings, and credit accounts

The core service online banking provides is access to manage existing bank accounts. Someone could hold multiple checking, savings, and credit accounts that they can access through a single login.

Users can access detailed transaction histories and statements for each account they hold. They can also:

  • Transfer money between accounts
  • Set up repeated internal transfers between accounts
  • Manage account features such as savings account buckets
  • Make transfers to external bank accounts without needing to write a check
  • Connect accounts with P2P services

Pay bills and statements online

People can pay bills online with direct ACH transfers. Many service providers, such as utility companies and property managers, prefer ACH payments, and users can set these up on a recurring basis to avoid forgetting to pay bills manually.

Account holders can also set up automated statement payments with both internal and external credit cards and loans. They can select how much they want to pay monthly, like the minimum payment or a specific amount, then set payments to repeat.

Connect to peer-to-peer networks

Peer-to-peer networks like PayPal allow users to connect bank accounts. With a connected account, they can make transfers and payments without exchanging bank information directly.

This is an added layer of privacy that allows people to shop online without entering account numbers and send money directly to people.

Apply for credit online

Banks offer many types of credit, including cards, personal loans, mortgages, and home equity lines of credit (HELOCs). Depending on the type, people can begin and sometimes complete applications online.

For example, many credit cards have entirely online application processes. On the other hand, more complex loans like HELOCs could require additional verification via phone and physical applications. In those cases, people can usually make a start online and then complete the process in-person.

Deposit checks

Online check deposits are a feature of mobile banking. It’s a convenient way to deposit checks without visiting a bank branch, but not all banks offer it.

How to cash a check online:

  • Log in to a bank’s mobile app.
  • Navigate to the “make a deposit” function, select an account, and enter the amount.
  • Endorse the check and follow additional instructions, for example, writing “for mobile deposit” and the institution name on the back of the check.
  • Photograph the front and back of the check.
  • Upload the photographs.
  • Keep the check for a few days to ensure it’s processed correctly.

Budget and plan finances

Online bank accounts can help people manage their finances with additional tools and data. Here are a few of the most common planning features:

Visualize spending based on categories: Banks collect information about the types of transactions people make, then sort them. This spending breakdown can help people track their spending and discover unnecessary expenses.

Learn about finances and budgeting: Banks want their members to have accounts in good standing, so they often provide learning resources to help people learn about finances and plan budgets. These could be articles in knowledge hubs, calculators, or access to more personalized advice.

Check credit score: Credit scores are complicated and determine what kinds of credit accounts and interest rates people can get. Many banks allow members to view their credit scores online and provide details about contributing factors.

Potential pros and cons of online banking

The pros and cons of online banking come down to convenience versus security.

Online banking is convenient because it lets users perform banking functions remotely and quickly. These features make online banking extremely common.

Online banking has security risks because there’s more potential for accounts to become compromised than traditional banking. It’s a lot easier to compromise an account accessed remotely via username and password than an account accessed in person at a bank branch.

Here’s a close look at the pros and cons:

The pros and cons of online banking.
Pros of online banking Cons of online banking
  • Available 24/7, allowing users to request actions at any time, and processing will start during business hours.
  • Secure access with encryption and authentication, like PayPal Security, helps protect accounts.
  • Efficient services, like near-instant account transfers, check deposits (with mobile banking), and bill payments, are typically faster online.
  • Digital statements help reduce paper waste, and there’s no waiting for them to arrive.
  • Instant alerts and updates about accounts are delivered via email or text, which can warn about suspicious account activity, low balances, and other issues.
  • Access to live support with accounts. Users can solve problems and get questions answered without visiting a branch.
  • Online bank accounts can be vulnerable to attack if users access accounts via unsecured networks.
  • Users may fall victim to fraud via social engineering or direct hacking.
  • Limited deposit options mean people must still deposit money (whether cash or checks) at physical branches.
  • Lack of face-to-face interaction with bank staff can make it difficult to get answers to complex questions. 
  • Technical errors and service interruptions can delay actions or create issues for users, so conducting urgent or important business in person is sometimes better.

Best practices for online banking

Having a positive experience with online banks is mostly about making sure a user's funds and transactions are secure. Generally, online banking can be safe if the platform offers security features and users exercise caution when accessing it.

Tips to help create a safe online banking experience:

  • Don’t access online bank accounts using public networks such as coffee shops and libraries; only use secure networks with restricted access, like a password-protected home network.
  • Never give passwords to people who ask for them over email, text, or phone.
  • Use information security software to track whether account information was involved in a data breach.
  • Sign up for bank security notifications.

A major part of what could make online banking unsafe is that remote access points create potential for fraud from external parties. However, people can limit these risks by watching for anything that looks odd. For example, users should also check that emails are legitimate before clicking links. Check for minor variations in the email address and the bank’s domain name.

For example, Chase Bank’s domain is chase.com, so all emails from Chase should end with “.chase.com" or "@chase.com” exactly. A scammer might use a variant email address like:

  • info@chasebank.com
  • customerservice@chase.org
  • c.support@chαse.com (Notice the difference between α and a.)

Send and receive money online with PayPal

Connecting an online bank account to PayPal allows users to send more to friends and family easily, as well as make purchases without providing bank information directly.

While PayPal is not a bank, users can connect it to their existing bank account and then send money in minutes, not business days.
