1. Go to Experiences > Authentication.
  2. Click + Add Policy.
  3. Enter a policy name.
  4. Select the type of policy for the first step, Login, Identifier First, or Multi-Factor Authentication. Because progressive profiling requires the user to be authenticated, it can't be the first step in the authentication policy.
    For more information, see: You can also use multi-factor authentication to set up passwordless authentication. See Setting up passwordless authentication.
  5. Click Add Step to add another step to the authentication policy (optional).
  6. Continue adding steps as needed for your authentication policy.
  7. Click Save.
Note:

The first step in a policy cannot have population or user attribute conditions. Additionally, if the second step in a two-step policy has conditions set, and you delete the first step so that the second step becomes first, those conditions will be removed.
