When you purchase a YouTube channel from someone, the process of gaining access on your phone is very simple and secure. A YouTube channel is essentially linked to a **Google Account (Gmail)**.
There are two primary ways to run it on your phone:
1. Primary Ownership Transfer (The Safest Method)
If you are conducting a professional deal, you should take ownership of the channel using your existing Gmail ID.
2. Process: The seller goes to the 'Permissions' settings in their YouTube Studio and invites your Gmail ID as an **'Owner.'
3. Accept: You will receive an invitation via email; you must accept it.
4. The 7-Day Rule: According to Google’s policy, after 7 days, you can become the Primary Owner and remove the previous owner. After this, the channel becomes entirely yours.
5.YouTube Studio App: Download the 'YT Studio' app from playstore to manage the channel, view analytics, and upload videos.
6. Switch Account: Click on 'Switch Account', and your newly purchased channel will appear there. The channel will automatically appear there as well.
Important Advice: Always try to use the **'Brand Account'** transfer method. This keeps your own Gmail secure and ensures the seller's access is completely revoked.
