Hi!

Hello! I am starting to use spreadsheets, email and other Zoho services. I don't understand why I need to log in using an email account from other services if I already have one from Zoho itself. For example, I am logging in with Gmail email to use spreadsheets and logging in with Yahoo email to use Zoho email. I also had difficulty with authentication because I had to use my wife's phone number because mine were already associated with other accounts. Why not link everything in one Zoho account? If it is possible, please help me to do this.
