If you want to log in to any service that Google offers, the place to start is with your Google Account at https://accounts.google.com/.
The login page will look like this:
- If you’ve forgotten what email address you use for your Google account, you can use this recovery tool.
- If you’ve forgotten your password, you’ll see a “Forgot password?” link after you enter your email address.
- If you’re still having trouble logging in, Google offers a lot of possible solutions on this page, but you will not find any Google customer service phone number, that is for sure.
