Every Credly member has their own unique public profile on Credly.com. You can customize the web address people use to visit your profile. Visit your "Account Settings" from the user menu at the top right of the site and look for the "Account URL" section. From there you can click the pencil to customize your unique Credly URL, and then click the "Save Changes" button.
Once you have set your Account URL, include it in on your resume, the signature of your emails, on your LinkedIn page, on your web site, Facebook page or blog, or in any communication where you'd like others to be aware of your recognition and achievement.
