In order to log into the Office 365 service, one needs to access the Office 365 homepage, by going to office.com. On the left-hand side of the Office 365 homepage, one will find the Office 365 login section.
Logging into office.com involves entering your email address, phone number, skype account, and your password.
What if you have forgotten your office.com password?
If you have forgotten your Office 365 service password, what you need to do is reset it before you will be allowed to login. Below the Office 365 account login page you will see options for email address and password, there is a link on the Office 365 login page labeled ‘Can’t access your account?’ and if you click on it, you will be sent to the Office 365 password reset page.
