# Manage 2FA for Brand Accounts
[Account Administrators](https://help.impact.com/brand/what-would-you-like-to-learn-about/account-administration/account-settings/invite-and-manage-users/understanding-user-management-as-a-brand) can require all impact.com brand account members to use two-factor authentication (2FA) when they sign in from a new device. Have questions about 2FA? Check our article on [Two-Factor Authentication FAQs](https://app.gitbook.com/s/hRN1rcrim887TwHLBjac/readme/two-factor-authentication-faqs).
When invited to join an account and your sign-up method involves using a username and password, you'll be automatically signed up for 2FA and your default authentication method will be set to email.
The user experience with 2FA enabled goes as follows:
* Upon first signing in, an account member will receive a verification code on their mobile device via SMS, email, or an authentication app.
* Once an account member has successfully been authenticated, their device will automatically be saved as a trusted device—meaning they won’t need to use 2FA on subsequent sign-ins. Account members will only be asked to use 2FA again if their device has changed or unusual activity was detected.
* Account members can manage saved devices on the impact.com user profile screen.
