Channel permissions provide you with the ability to give other users access to your channel via specific roles. Designating roles allows you to choose the correct level of access. Migrate to channel permissions to prevent security risks such as password sharing and minimize other privacy concerns.
If a YouTube channel is linked to a Brand Account, various members can manage the channel from their Google Accounts. You don't need a separate username or password to manage YouTube channels with a Brand Account. A Brand Account can be linked to a YouTube channel but not other Google Services.
First, check if your channel is connected to a Brand Account. If it's not, you can change channel managers, but not owners. To transfer channel ownership, convert to a Brand Account by removing all roles in the permissions set up.
Troubleshoot adding roles to Brand Accounts
You should use channel permissions to manage user access to your channel.
If you need to use Brand Account roles (not recommended), and are having trouble adding others, you may need to opt out of channel permissions and opt back in later. To switch back to your Brand Account, you must invite everyone to the Brand Account again.
To opt out, select “Opt out of permissions in YouTube Studio” under YouTube Studio's Settings 
View or add roles to your Brand Account
Only use Brand Account roles if needed. It’s important to grant the appropriate access level to users to avoid security issues. Avoid unsafe practices like sharing passwords.
It’s the channel owner's responsibility to know their Brand Account’s ownership details. It’s recommended that you regularly check Brand Account permissions to maintain account security.
