Use a pre-Google YouTube account (legacy YouTube account)
Channels that were created before May 2009, and haven't been signed in since 2011, are not part of a Google Account. These are called "legacy YouTube channels."
To access a legacy channel, you need to link it to a Google Account:
- Go to accounts.google.com/login and sign in to the Google Account you'd like to link with your YouTube channel. If you don't have a Google Account, you can create one.
- Go to youtube.com/gaia_link.
- In the box on the left, enter your YouTube username and password.
- Select Link these accounts.
- Select Claim channel.
After you complete these steps, use your Google Account username and password to access your YouTube channel.
