What to expect after activating two-step verification
The next time you log in to a HarvardKey-protected resource, you will be prompted to log in with your preferred authentication method. Call Me is the recommended method for landline users. You can also check the box "Remember me for 30 days" on this screen. This will allow you to verify your identity only once a month (per browser).
