What is SingleSign?
SingleSign is a free sign-in service. When an app or website supports SingleSign, you can use your SingleSign account to sign in — no need to create a separate account for each app.
How it works
-
One account, many apps. You create a SingleSign account once. Then, whenever you visit an app that supports SingleSign, you can sign in with that same account.
-
You control your data. When you sign in to an app for the first time, SingleSign shows you exactly what information the app is asking to access — like your email address or display name. You decide whether to allow it.
-
Revoke access anytime. Changed your mind about an app? You can disconnect it from your SingleSign account at any time, and it will no longer have access to your information.
Why use SingleSign?
- Fewer passwords to remember. One account covers all the apps that support SingleSign.
- Stronger security. You can protect your SingleSign account with multi-factor authentication (MFA), which adds an extra layer of security to every app you sign in to.
- Transparency. You always know exactly what data each app can access, and you can review or revoke permissions whenever you want.
- It's free. SingleSign is free for consumers. You'll never be charged to create an account or sign in to apps.
What SingleSign is NOT
- SingleSign does not store your passwords for other websites (it's not a password manager).
- SingleSign does not track your browsing activity.
- SingleSign does not share your information with apps without your explicit consent.
