Whether you have multiple products using Recurly, or have a production, sandbox, developer, and QA site, Recurly makes it simple to navigate between each site with just one set of credentials.
To access a Recurly site from a specific account, just follow these steps:
Access your user role page
Click Invite User
Enter the email address of your main Recurly account
Choose their access level permissions, then click Invite User
When you log in under this email address, you'll now have a drop down menu at the top of your site (see above image) that allows you to quickly switch between sites. Contact Recurly Support if you have any questions about this feature or would like more pro tips!
