What is SSL?
SSL stands for Secure Socket Layer. It is a technology that secures the connection between your browser and the website you are visiting. To verify SSL connection, check to see if the prefix https is used.
Adobe Portfolio and SSL:
SSL Certificates are currently only supported on all Adobe Portfolio URLs (ex. yourname.myportfolio.com), meaning the prefix https is supported for Portfolio URLs.
SSL is not currently supported on custom domains - the prefix http is used on custom domains. We are working towards supporting SSL certificates in the future, stay tuned!
