Done registering your token? Then you still have to activate your token. Depending on your situation or the requirements of your institution, you must choose an activation method, or you will immediately see instructions for the method that is right for you:
- Activate yourself; you do this by choosing a recovery method (SMS or recovery code).
- Activate at a service desk. Do this within 14 days, because your activation code expires after 14 days
- Activate with an existing token.
