Verification codes are valid for a limited amount of time. If your code expires, you’ll need to request a new code.
If you click Resend Code, the previous code you requested becomes invalid. Sometimes it takes a minute or so for your code to arrive, so wait at least a few minutes before you click Resend Code. If you’ve requested multiple codes, be sure to enter the most recent code received.
To avoid a mistake when typing your verification code, try copying and pasting the code into any of the verification code boxes.
