What do I need to sign in?

To sign in to Microsoft 365, you need a reg­is­tered Microsoft account, which can be a personal account, a uni­ver­si­ty or school account, or a business account. Basic Microsoft accounts are free. Costs only arise if you decide to buy Microsoft 365 as a one-time purchase or sign up for a premium plan. These are split into Personal and Family plans, but there are also plans for small, medium and large busi­ness­es. Each free Microsoft account includes 5 GB of OneDrive cloud storage. If you don’t have a Microsoft account yet, you can create one here: https://account.microsoft.com/.

What sign-in options are there?

When Microsoft prompts you to enter your cre­den­tials, the sign-in sequence can vary depending on whether you have two-step au­then­ti­ca­tion enabled. By default, you sign in with an email account and a secure password. With two-factor au­then­ti­ca­tion, you can sign in via a phone call, text message or Microsoft Au­then­ti­ca­tion app, virtually elim­i­nat­ing the pos­si­bil­i­ty for third-party access.

Which programs can I use after signing in?

With a free Microsoft account, you have access to the web app versions of some of the most important pro­duc­tiv­i­ty apps and Microsoft services. The range of apps available depends on the type of sub­scrip­tion you have. You can access the apps directly from your account via the apps overview.
