Enable Single Sign-On to Dropbox with UserLock

Centralize Dropbox authentication with UserLock SSO to simplify access for users while retaining full control over corporate accounts.

Published September 26, 2025

Introduction

This guide explains how to integrate Dropbox with UserLock Single Sign-On (SSO) using the SAML 2.0 protocol.

Once configured, Dropbox logins are authenticated by UserLock. This provides users with a seamless sign-in experience and allows administrators to enforce UserLock access policies (MFA, time, machine, or location restrictions) on SSO sessions.

🚩️ Before starting:

Step 1. Enable Dropbox in UserLock SSO

  1. In the UserLock console, go to ⚙️ Server settings ▸ Single Sign-On.

  2. In the application list, select Dropbox.

  3. When prompted, enter the Email domain to be used for user logins.

  4. Save the profile.

Step 2. Configure Dropbox for Single Sign-On

  1. Sign in to Dropbox Admin Console with an administrator account.

  2. Go to ⚙️Server settings ▸ Single Sign-On.

  3. Complete the form with the following values:

    X.509 certificate

To cancel SSO and revert to standard logins:

  • Set the Single sign-on drop-down list value to Off.
