Single Sign-On

One login with multi-factor authentication for the business apps your team uses, and offboarding that removes access everywhere at once.

Single sign-on, or SSO, lets staff use one account to sign in to many business applications. 1REALTOUR sets up SSO for small teams, connects their apps, enforces multi-factor authentication and makes offboarding a single step. It is for businesses where every app has its own password, shared logins are common and nobody is sure who still has access.

The problem with separate logins

A typical small business uses many web applications: email, CRM, accounting, help desk, website admin, file storage, scheduling and more. Each has its own password, often reused or shared. When someone leaves, access has to be removed from each app by hand, and something is usually missed.

SSO puts one identity in charge. Staff sign in once, apps trust that sign-in, and access is granted or removed in one place. There is also one sign-in log to review, so unusual activity across all your apps can be spotted from a single screen.

What we set up

  • A central identity provider for your team, or configuration of the one you already use, such as Google Workspace or Microsoft
  • Connections to apps that support standard protocols such as SAML and OpenID Connect
  • Multi-factor authentication required for every account
  • Groups and roles so each person sees only the apps they need
  • A login portal that lists each person's apps
  • Protection for internal tools that have no login of their own

For self-hosted tools and internal dashboards that lack built-in SSO, we can place them behind an authenticating proxy so nobody reaches them without signing in first.

Stronger multi-factor authentication

Not all multi-factor methods are equal. CISA describes FIDO and WebAuthn authentication, such as passkeys and hardware security keys, as the only widely available phishing-resistant option, while noting that any MFA is better than none. We help teams move to passkeys or security keys for administrator and finance accounts first, and use authenticator apps where those are not practical. Text message codes are kept as a last resort. Recovery matters too: we set up backup sign-in methods and a documented reset process so a lost phone does not lock anyone out for days.

Onboarding and offboarding

With SSO, adding a new employee means creating one account and placing it in the right groups. Removing someone means disabling one account, which ends their access to every connected app. We document both steps so your office manager can do them without calling IT.

Shared accounts and passwords

Some services still require a shared login. Those go into a team password manager with access controlled by the same groups, so a departing employee loses access to shared passwords as well. We also review which apps can be connected to SSO and which plan level each vendor requires, since some vendors include SSO only in higher tiers.

What's included

  • App and account inventory
  • Identity provider setup or configuration
  • SAML and OpenID Connect app connections
  • Required multi-factor authentication
  • Passkey and security key rollout for key accounts
  • Groups, roles and app access rules
  • Proxy login for internal tools
  • Onboarding and offboarding procedures

How we work

  1. Step 1

    Inventory

    We list every app, who uses it, how they sign in and whether it supports SSO.

  2. Step 2

    Design

    We choose the identity provider and define groups, roles and MFA rules.

  3. Step 3

    Connect

    We connect apps one at a time and move each user to the new sign-in.

  4. Step 4

    Hand off

    We document onboarding and offboarding and train the person who manages accounts.

Frequently asked questions

What is single sign-on?
Single sign-on is a method that lets a person sign in once with one account and then access many applications without separate passwords. The applications trust a central identity provider to confirm who the person is.
Is single sign-on worth it for a small team?
Single sign-on is often worth it for small teams because it enforces multi-factor authentication everywhere, removes shared passwords and makes offboarding a single step. The time saved on password resets and access changes adds up quickly.
Which apps work with single sign-on?
Apps that support standard protocols such as SAML or OpenID Connect can connect to single sign-on. Many business apps support one of them, though some vendors offer SSO only on higher plans. 1REALTOUR reviews each app before setup.
What is phishing-resistant MFA?
Phishing-resistant MFA is multi-factor authentication that cannot be captured and replayed by a fake login page. CISA identifies FIDO and WebAuthn methods, such as passkeys and hardware security keys, as the widely available phishing-resistant option.
Can single sign-on protect tools that have no login?
Single sign-on can protect internal tools that have no login of their own by placing them behind an authenticating proxy. Users must sign in through the identity provider before the tool loads.
