There are a few reasons that an "invalid error code might occur:
Setup is incomplete
Each QR code used for setting up two-factor authentication is valid only for a limited time, usually a few minutes. If setup isn't completed before the code expires, the account added to your authenticator won't work. To resolve:
- Remove the Code42 account previously added to your authenticator. Do not skip this step.
- Refresh the sign in page in your web browser and sign in again, if prompted.
- Scan the QR code or manually enter the code as a new account in your authenticator.
- Enter the verification code from your authenticator in the last step of the sign in screen.
Entering a code from a different account
If you have multiple two-factor authentication accounts set up in your authenticator, you may accidentally enter the code corresponding to a different account. Double-check the account associated with the code you are using and try again.
Device time is out of sync
