In order to access your certification dashboard from the Andela Talent Cloud upon signup, you'll need to accept the welcome invitation that was emailed to you within 24 hours. If you don't activate your account within that timeframe, you'll receive a "Token Expired" error like this:
Solution: If you need a new activation token, just return to the Andela Talent Cloud and sign up again. This will generate a new token for you, and you'll receive another account activation email with a new token. Remember to activate your account within 24 hours. Please note that you will not lose your application progress when signing up again.
