What is the Coinbase Authenticator app, and how do I use it?

The Coinbase Authenticator app is an additional security layer for your Coinbase account, providing a more secure method for two-factor authentication (2FA) compared to SMS. To use it, one must first download the app from the App Store or Google Play, depending on their device. After installation, you link it to your Coinbase account by scanning a QR code provided in the account's security settings. Whenever prompted for 2FA when logging in or performing sensitive operations, the app generates a one-time-use passcode that must be entered to proceed. This reduces the risks associated with SMS-based 2FA, such as SIM swapping attacks, enhancing the overall security of your Coinbase account.
