3. What do I need to create an or account?

You will need the email address associated with your IPP account. You will also need to provide a valid mobile phone number or a landline without an extension.  

4. What email address do I use to create an or account?

Use your IPP account email address, so we can automatically link your IPP account to your or account. If you use a different email address, we will not be able to link your account.

This process only works if the or email address in the sign-in process is the same as your IPP account email address. 

5. Will I be able to use a group email address?

When creating an or account, you will be required to confirm your email address. Confirming your email address certifies that you are the owner of the email address you provided. You will also be asked to set up multi-factor authentication to secure your account. After you set up MFA for your account, to sign in, you will enter your email address and password, and confirm your sign-in using the MFA method you choose. This will require you to have access to a smartphone, landline without extension, or a tablet.

8. Can I use a different email address from my IPP account email address, when setting up my or account?

When you first create your or account, you must use the same email address you currently use for signing in to IPP. This will then automatically link your IPP account information to your new or account.

9. Can I share an or account and profile with another person within my organization?

No, you cannot share an or account and profile with another person or use a group email address to create a new account. Each user must create an or account and go through an identity verification process to get access to IPP.
