Error 16434: Multi-factor authentication code is invalid or already used. Wait for a new code and try again.

Problem description

When using Wedge web interface or API, I’m getting an error:

Error 16434: Multi-factor authentication code is invalid or already used. Wait for a new code and try again.

Cause

  1. You made a typo in the MFA code.
  2. Multi-factor authentication method allows using each authentication code only once. The code that you have been trying to use is probably been already used.
  3. Multi-factor authentication method allows to use of each authentication code only in a short period, usually about 1 minute. You have been trying to use “outdated” code.

Solution

Check your MFA code or wait for a new one, then try again.
