    As a native Android app developer of 5 years, I am curious about the limitations that prevent accounts with “custom” domains – domains other than protonmail.com – from being accessed on mobile devices via your app. I am familiar with PGP, DES, Android privileges etc. and some legal issues regarding encryption and intellectual property yet I cannot imagine any root cause behind why I cannot use my new account on my mobile device.

    You would log in to sub-user accounts the same way as when using the web client, using the entire custom domain address. If you are having a different issue, please contact our support team at contact@protonmail.com or using the support form at https://protonmail.com/support-form.

    To add more than 10 custom domains, you will need to upgrade to our Professional plan. Using the Professional plan you can add up to 50 custom domains. https://protonmail.com/support/knowledge-base/business/
