Where: Trailblazer.me is available to AppExchange, Events, IdeaExchange, Trailblazer Community, and Trailhead users. Partner Community doesn't use Trailblazer.me features, but Trailblazer.me shares some profile data with the Partner Community profile.
When: Trailblazer.me is generally available in January 2020.
Why: You have a lot of usernames and passwords to remember. You have different profiles on Salesforce-related sites like Trailhead and Trailblazer Community. With Trailblazer.me, we combined all those accounts so you access any of the sites with one login. Switch between the sites using the Application Launcher.
And you manage your profile on all of them at once. Your Trailblazer.me profile shows aggregated data across all the sites and all your users—if you have more than one. To see or edit your Trailblazer.me profile, click your profile pic and select Profile. If your profile is set to public, you can use it like a digital resume. Show it off so coworkers and future employers can see your Trailhead skills, your winning ideas, and your helpful community posts.
How: The first time you log in to a Salesforce-related site after Trailblazer.me is generally available, you see a prompt to enter or update some profile information. If Trailblazer.me recognizes any additional accounts of yours, they’re merged. You can manually merge accounts on the Settings page.
