Security is a vital part of managing finances in today’s world. A personal identification number, or PIN, is a simple yet powerful tool used to protect financial transactions. A PIN is a unique code, usually made up of four to six numbers, that confirms the identity of the person making a payment or withdrawal.
This article includes tips, suggestions, and general information. We recommend that you always do your own research and consider getting independent tax, financial, and legal advice before making any important decision.
The main purpose of a PIN is to add an extra layer of security, ensuring that only the rightful owner of a debit or credit card can use it. By requiring a PIN, financial institutions help prevent unauthorised access to accounts and protect against fraud.
This article will explain what a PIN code is, why it’s important, and how it’s used to keep financial transactions secure.
PIN security is a crucial measure to safely access financial accounts. It's most used at ATMs or during a purchase as a way of ensuring only the authorised cardholder can access funds or approve transactions. The practice has since spread to cybersecurity, with many computers, phones, and tablets now protected by PINs.
PayPal’s security features are in place to help prevent unauthorised access to accounts and devices, keeping them secure.
At ATMs, entering the correct credit card PIN or debit card PIN allows for cash withdrawals, balance inquiries, and other banking services. At point-of-sale (POS) terminals, PINs help to confirm the identity of the cardholder during purchases. This is why it is so vital to keep a PIN secret.
In the UK, chip and PIN technology further enhances security. This system combines a microchip embedded in credit cards or debit cards with the cardholder’s PIN to authenticate transactions, offering more robust protection against fraud compared to older, signature-based methods.
When setting up a digital wallet, such as PayPal, a PIN is typically created to unlock the wallet app.
Certain digital wallets distinguish between a login PIN and a transaction PIN. The login PIN is used to access the wallet, whereas the transaction PIN is required to authorise payments or transactions.
Implementing a digital wallet PIN for accessing the wallet and confirming transactions enhances security, making digital wallets a reliable option for managing and spending money online.
Allowing others, even family and close friends, to know a PIN is inherently risky. Writing it down and keeping it in a wallet or as a note on a phone is also unsafe. These all raise the likelihood that someone will access it and use it to steal funds.
When it comes to how to keep your PIN safe, it’s recommended to memorize it rather than write it down. Additionally, avoid using easily guessable numbers, such as birthdates, and change the PIN periodically to enhance security.
PIN scams are a prevalent threat, often involving phishing attempts or social engineering tactics. Scammers may try to trick individuals into revealing their PIN through fake emails, texts, or calls posing as legitimate companies. These scams often create a sense of urgency or fear, prompting individuals to disclose their PIN without realizing the risk.
Also be cautious of unsolicited communications requesting PIN information. Legitimate companies will never ask for a PIN via phone or text. Always verify the source of any such requests before taking action.

What is a strong PIN? It avoids using easily guessable information, such as birthdates, anniversaries, or simple sequences like "1111" or "12345." Using a mix of numbers can further enhance security, and choosing a PIN that is both unique and difficult to guess will help protect your account.
Many digital wallets and cards now offer biometric authentication, such as fingerprint or facial recognition, as an alternative to PINs. These methods provide an additional layer of security to protect your devices, making it more difficult for unauthorised individuals to access accounts.
A forgotten PIN can be inconvenient, but retrieving or resetting it is usually straightforward. If the PIN for a card is forgotten, the first step is usually to contact the card provider or bank. They may offer options to reset the PIN online, through a mobile app, or by visiting a branch. It is often easy to find out how to reset a PIN on the websites or apps of banks and financial service providers.
For example, if a PayPal PIN is forgotten, users can reset it by logging into their account and following the provided security steps, or by reaching out to PayPal's customer support for assistance.
Creating a strong, unique PIN is a vital part of keeping finances safe and reducing the risk of fraud.
PayPal offers robust security features, including PINs and biometric authentication, ensuring that accounts are protected through advanced encryption methods.
