Coinbase security measures

Coinbase is a leading American crypto exchange launched in 2012. It offers various deposit methods and supports major cryptocurrencies. It is considered a secure platform with multiple security measures in place to protect users' bank details and personal information.

Coinbase uses AES-256 encryption, the industry standard used by banks, to secure sensitive information like bank account numbers and routing details. This encryption ensures that data stored on Coinbase servers is unreadable without proper authorisation. Additionally, Coinbase employs two-factor authentication (2FA) and biometrics for customer login, adding an extra layer of security.

To protect users' privacy, Coinbase performs background checks on its employees and utilises role-based permissions to restrict access to customer data. Only authorised employees with specific job functions can access sensitive information, and even then, it is limited. When connecting your bank account to Coinbase, your username and password are securely handled by Plaid, a third-party service. Coinbase receives only the account details necessary for verification and fraud prevention, such as your account number and balance, not your password.

Coinbase also offers a crime insurance policy that covers a portion of custodial crypto assets in case of data breaches or theft. However, it is important to note that this insurance does not cover losses from unauthorised access to your Coinbase account, NFTs, or potential full reimbursement if losses exceed insurance recoveries.

While Coinbase has implemented robust security measures, no platform is entirely immune to security threats. There have been incidents of notable hacks and breaches at Coinbase, as well as concerns about the security of Plaid, the third-party service used for bank account linking. Therefore, it is essential for users to remain vigilant, enable two-factor authentication, and take necessary precautions to protect their bank details and personal information.

Bank account linking issues

Linking your bank account to Coinbase is considered safe, with private information protected similarly to banks. Passwords are hashed with bcrypt, wallets and keys are AES-256 encrypted, and any withdrawal requires user permission and two-factor authentication. Coinbase is insured by the FDIC for up to $250,000 for US residents, uses encrypted SSL for website traffic, and stores 98% of funds in cold storage. Employee security measures are stringent, including criminal background checks and encrypted hard drives.

However, there have been some issues reported by users trying to link their bank accounts to Coinbase. Some users have reported server issues, while others have reported that they were unable to link their bank accounts even after following the troubleshooting steps provided by Coinbase. One user suggested changing the URL to coinbase.com/verify-document and completing the verification process again.

It's important to note that linking a bank account to Coinbase is only available in certain regions, including the US, most of the EU, and the UK. In some cases, you may need to contact your bank for assistance. Additionally, there are specific verification processes for different types of bank accounts. For traditional bank accounts, Coinbase will send two small verification amounts to your bank account, which you must then enter correctly in your payment settings. These amounts may appear in your upcoming or pending transactions, or you may need to check your full bank statement. For "online banks" or similar banking products, you may not receive the verification credits, and you will need to try another bank account. For cards, Coinbase will make two test charges of amounts between 1.01 and 1.99 in your local currency, which will appear as pending or processing charges. If you don't see the verification amounts after 24 hours, you should contact your bank or card issuer to ask for the amounts of any pending Coinbase authorizations.

Plaid and data sharing

When you connect your bank account to Coinbase, you are prompted to use Plaid to link your accounts. Plaid is a technology that provides connections to more than 11,000 US banks and credit unions. It helps you securely link your financial accounts to apps.

Plaid collects, uses, and shares your data when you use its products or services. It is committed to providing end users with meaningful control over their data. It does not sell your data to any outside companies and only shares your data with your permission. It is regularly audited by security researchers and financial institutions.

When you connect your financial accounts to an app using Plaid, you will be prompted to enter the username and password associated with those accounts. Plaid then links your accounts to the app you want to use so you can share your data. Plaid does not share the username and password for your financial institution with your apps. Once you give permission to share your financial data, it is securely transferred from your financial institution to the app through Plaid's application programming interface (API).

Plaid also provides tools to easily delete your data from its systems as well as connect, manage and disconnect your fintech apps.
