This was the old method but is very useful besides adding our mobile number as the trusted number.
To add your Apple Developer Account to our Apple Developer Account you need to grant access to your account in two places:
- App Store Connect and;
- Apple Developer website.
Please review the two articles below for instructions on how to grant admin rights:
1. App Store Connect - Adding Team Members
2. Apple Developer - Adding Team Members
Don't forget to add our trusted mobile number. Please email us for that number.
See Add trusted number.
