You may see an "invalid security code" error or may be unable to complete two-factor authentication (2FA) when signing in to your Norton account using a mobile authenticator app. This article explains the common reasons why the security code might not work and guides you through the steps to resolve the issue.
Authenticator codes are only valid for 30 seconds. If you enter it just as it is expiring, it might be rejected.
You might be viewing the wrong entry in the authenticator app, especially if you have multiple accounts.
A typical example of how the account name for Norton 2FA may appear in a mobile authenticator app is: SOTP-S3pCVmV. This label helps you identify which account the code belongs to, especially when multiple accounts are added to the app
Mobile authenticator apps (like Google Authenticator, Microsoft Authenticator, or Authy) generate time-based one-time passwords (TOTP). If the time on your phone is not in sync with the server, the codes may be incorrect.
Try choosing different methods, if available.
If the steps above do not work, contact Norton Support.
