Give your team a faster, safer way to sign and send documents. With SSO, employees sign in to SignNow using the same corporate credentials they use elsewhere—so access is seamless, security policies are consistent, and IT spends less time on account fixes. You get centralized control (MFA, password policies), smoother onboarding/offboarding, and clear audit trails for compliance. This guide shows you how to connect your identity provider (IdP), validate the connection, and roll SSO out to your users with minimal disruption.
What is SSO?
Single Sign-On (SSO) lets users authenticate to multiple apps (like SignNow) using one trusted identity provider and one set of credentials. The IdP verifies the user and securely passes a signed assertion/token to SignNow to grant access.
Why use SSO?
Stronger security: Enforce MFA, password rotation, and conditional access centrally.
Simpler UX: One login for many apps reduces friction and lockouts.
Faster IT ops: Provision and de-provision users once; fewer reset tickets.
Compliance & audits: Centralized access controls and consistent logs.
Reduced risk: Immediate access revocation when employees change roles or leave.
This guide explains how IT Administrators can enable Single Sign-On (SSO) in SignNow to simplify user management through your existing IAM system. This allows you to control access for specific user groups and streamline onboarding and offboarding.
Prerequisites
You must have a Site License subscription with SignNow.
You must be an Organization or Workspace Administrator in SignNow.
Your company must already manage employees via an IAM provider (e.g., Okta, Azure AD).
You need to know the details of your identity provider’s authentication settings (SAML or OIDC).
Overview of the Setup Process
Access the SSO configuration page in SignNow.
Set up the connection between SignNow and your IAM system.
Enable SSO for your organization.
(Optional) Enforce "SSO only" login.
Manage users through your IAM system going forward.
Step-by-Step Instructions
Step 1: Access the SSO Configuration Page
Log in to your SignNow Administrator account.
Go to Settings > Organization Settings (or Workspace Settings, depending on your plan).
Locate the SSO Configuration section under My Account tab.
A "New" badge highlights this section if you haven’t accessed it before.Click on the Set up SSO.
If your plan does not include a Site License, a paywall will appear with an option to Contact Sales.
Step 2: Complete the SSO Setup Flow
After clicking Set up SSO, a setup window will open.
Follow the configuration steps.
Name your configuration.
Verify your domain to confirm ownership.
Provide IAM provider details (e.g., SAML URLs, certificates, or OIDC endpoints).
3. Review and confirm the configuration.
📝 You can create multiple configurations, but only one can be active per workspace.
Step 3: Enable SSO for Your Workspace
1. Once your configuration is saved, return to the SSO Configuration page.
2. Use the toggle to Enable SSO Login for this Workspace.
3. Until enabled, users will continue to sign in using existing methods.
Step 4: (Optional) Enforce "SSO Only" Login
If you want all workspace members to log in exclusively through your SSO provider, enable the SSO Only option under the Workspace settings. This disables email/password and social login methods.
Managing Users After SSO Is Enabled
Control access to SignNow through your IAM tool.
Add or remove users from your designated IAM groups to onboard or offboard employees automatically.
Existing users tied to your domain will authenticate through your IAM after SSO is activated.
Managing SSO Configurations
From the SSO Configuration page, you can:
Edit – Reopen the setup flow to make changes.
Show Links – View configuration details for your IAM provider.
Delete – Remove the configuration (users will no longer authenticate via SSO for that setup).
Notifications and Promotion for SSO
You will see a notification about SSO after inviting your third user to your workspace.
If you already have 3+ members, you will see this notification after logging in.
From the notification, you can:
Click Set Up SSO to go directly to the setup page.
Click Learn More to access related documentation.
Existing Customers with Legacy SSO Setups
If your organization already has a connected SSO domain, this will be displayed in the SSO settings.
These configurations cannot be edited through the new setup flow. Contact SignNow Support for changes.
You can still enable or disable the SSO Only option.
Contacting Sales if Not Subscribed to Site License
If you are not on a Site License plan:
Clicking Set up SSO will show a paywall.
Complete the Contact Sales form with your details (name, email, phone, company size).
Your request will be submitted for follow-up.
Frequently Asked Questions
Can I test the setup before enforcing it for everyone?
Yes. The configuration is saved but inactive until you enable it manually.
What happens if I delete an SSO configuration?
Users will revert to email/password or social login unless you add a new active configuration.
Can I have multiple configurations?
Yes, but only one can be active per workspace at any time.
What is the “SSO Only” option?
This setting forces all users to authenticate through your IAM provider, disabling all other login methods.
