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 minimise 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 how to add 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.
To find out who manages your Brand Account:
- Go to the Brand Accounts section of your Google Account.
- Under 'Your Brand Accounts', select the account that you want to view.
- Select Manage permissions. You will find a list of people who can manage the account, including owners.
To invite new people to your Brand Account:
- To invite new people, choose Invite new users
.
- Enter their email addresses.
- Below their names, choose their role:
- Owners can take the most actions and they control who manages the account. An account must have one primary owner.
- Managers can use Google services that support Brand Accounts (e.g. sharing photos on Google Photos or posting videos on YouTube).
- Communications managers can do the same actions as Managers but they can't use YouTube.
- Tap Invite
Done.
.Anyone who you invite will get an email in which they can accept your invitation.
Set yourself as primary owner of your Brand Account
In addition to having one primary owner on the Brand Account, it's recommended that you have at least one other owner associated with your Brand Account.
If you can't designate a new primary owner, verify that you're opted out of channel permissions. Managers will not have the option to change the primary owner role.
- On your computer, go to the Brand Accounts section of your Google Account.
- Under 'Your Brand Accounts', select the account that you want to manage.
- Click Manage permissions.
- Find your name listed.
- Tip: If you can't find your name, you must be added as an owner by another channel owner. After accepting the invite and waiting seven days, try again from Step 1.
- Next to your name, click the down arrow
