How to sign into YouTube without Google account
Unfortunately, it is not currently possible to sign into YouTube without a Google account. YouTube is owned by Google, and as such, it requires users to have a Google account to sign in and use the platform.
If you do not have a Google account and do not wish to create one, you can still view videos on YouTube without signing in. However, you will not be able to like, comment, or upload videos without a Google account.
If you are concerned about privacy or do not want to use your personal Google account, you can create a new Google account specifically for YouTube. This will allow you to keep your YouTube activity separate from your other Google services. Alternatively, you can use a third-party service to access YouTube, although these services may not provide the same functionality as the official YouTube app or website.
