What is two-factor authentication (2FA)?

Two-factor authentication (2FA) requires you to input two types of identification (“factors”) when logging into an online account, offering an extra layer of security to help protect your accounts and information from unauthorized access. You may also be prompted to enter a 2FA one-time code for other actions in Digital Banking, such as changing a phone number or email address or adding a linked account.

2FA improves upon the traditional username/password-based login format by requiring the additional form of identification. Think of two-factor authentication (2FA) as a “double lock” on your online accounts.
