Issue Resolution
The main reason that this can happen is due to a typo in the email address that communication is sent to for your login. If you are not receiving the device authorization email, reach out to Marketo support by emailing support@marketo.com and we can manually authorize your device or location.

To prevent this behavior from continuing to take place we recommend you do the following:

- After you’ve gained entry into the Marketo instance, we recommend you visit Admin > Users & Roles and confirm that the email address listed is spelled correctly.
- Validate with your IT team to ensure that Marketo is whitelisted using these IP addresses: Whitelist Marketo IPs
