If you are invited into a second instance with Universal ID (UID) enabled, you will need to follow the process below to ensure that you are accessing your second instance correctly. IMPORTANT NOTE: When an admin user in Marketo is inviting you into a second instance, in order for Universal ID to work correctly they will need to invite you with the exact same Marketo Login name and Email. Doing this correctly will allow you to toggle between both instances with UID.
1. Open up your Marketo new user invite email with the subject "Marketo Login Information" from no-reply@marketo.com. Click on the "Login to Marketo" hyperlink in the email
2. You will be taken to a 'Login page'. NOTE: When you are invited into your very first instance you are taken to the 'Create a Password' page but since this is your second or third or fourth instance you have been invited into with UID, you will be prompted with the login page below.
You will enter your login credentials for your original Marketo instance, click on the "I accept the terms and conditions" checkbox, and then select the sign-in button.
3. You will be logged into the new Marketo instance and you should see a grey arrow next to the instance name in the upper right-hand corner. You can click on the instance name, and you should see a drop-down with all the instances you have access to (in this case just 2).
You should now be all set! If you have any issues with that process, you can reach out to the Customer eXperience and Identity team (CXI) for further assistance by emailing customercare@marketo.com.
