I want to create 4 different YouTube channels !

YouTube track device fingerprint IPs, not just hardware., To run 4 separate channel, use different Google account, isolated browser, and build real activity on each account to achieve trust.

To create 4 separate YouTube channels without using multiple computers, consider using an antidetect browser. It allows you to manage different accounts while masking your device's fingerprints and IP. This helps avoid YouTube linking your accounts and treating them as from the same source.
