Overview The Synchronization feature in Hidemyacc lets you manage multiple profiles at once and synchronize actions across all selected profiles. With this feature, you can quickly replicate an action performed in one profile across other profiles, saving time and effort. {% hint style="info" %} **Video guide:** {% endhint %} When synchronizing actions between profiles, you need to understand 2 types of profiles: * **Main profile:** The primary profile. Any action you perform in this profile's window will be simultaneously replicated across the other profiles. * **Controlled profile:** A controlled profile synchronizes all actions performed in the main profile's window. The first profile you select becomes the Main profile. Subsequently selected profiles become controlled profiles. Pay attention to the order in which you select profiles, as it affects subsequent actions. To switch which profile is "Main," click this icon on the profile you want to promote to the main profile. Clicking this icon will bring that profile's window to the front.
