You need to be able to login to my.wpengine.com
To do this, you’ll just need to reference the initial email that WP Engine sent you when you signed up.
The email has a Subject of “You have been invited to the WP Engine Portal” and looks something like this:
Search or check your archived emails if you’re having trouble finding it.
Click the the link in the email that says “Accept the invitation“
You will then come to a page where you can set your password. Strong passwords are a requirement and the page gives you hints on exactly how to create a strong password.
Once you have entered a strong password, you’ll be taken to the Dashboard and that’s it, you’re finished!
