Set up Your Preferences for Two-Factor Authentication (2FA)
Authenticator apps for generating 2FA verification codes are supported in all NetSuite accounts. Authenticator apps can generate a verification code even without a cell service. For more information about selecting an authenticator app, see Supported Authenticator Apps.
You can skip the prompt to set up 2FA five times before you are required to select an authentication method and set up your authenticator app. Ten backup codes are generated when you complete the security setup page.
When using an authenticator app for 2FA, you must enter the verification code obtained from the app to complete the setup.
If you want to change your 2FA preferences, you must reset your 2FA settings. For more information, see Reset Your 2FA Settings. This includes changing a device used for 2FA, or changing your authenticator app.
If you were not faced with a 2FA challenge last time you logged in NetSuite, you will need a verification code, backup code, or a help from your Administrator. If you can, reset your 2FA settings before you change your authenticator app.
