Single Sign On
Signing in once with one account to reach many applications.
What Single Sign On means
With single sign on, applications trust a central identity provider such as Microsoft Entra ID rather than keeping their own passwords. The user signs in once; each application asks the provider whether that person is allowed in. Access decisions and policies then live in one place.
Why Single Sign On matters for small businesses and nonprofits
For a small team the benefit is control. When someone leaves, disabling one account closes every connected application at once, instead of hoping somebody remembers the eleven separate logins.
What to do about Single Sign On
- Connect your most important applications to your identity provider first
- Enforce multi factor authentication at the provider so it applies everywhere
- Keep an inventory of applications that cannot be connected, and treat them as exceptions
