Single sign-on
Single sign, stay signed in—use one account to access many websites and apps.

What it means
Single sign-on, or SSO, is a way to log in to multiple services with just one set of login details. Instead of creating separate accounts for every website or app you use, SSO lets you use one account to access them all. This is especially useful for businesses that have many tools and platforms.
Why it matters
SSO simplifies your digital life by reducing the number of passwords you need to remember. This can help you avoid using weak or repeated passwords, which are easier to guess or steal. However, it also means that if your main account is compromised, all the linked services could be at risk. That’s why it’s important to use strong passwords and enable two-factor authentication for your SSO account.
What to do
If you use SSO, make sure you:
- Use a strong, unique password for your SSO account.
- Enable two-factor authentication.
- Regularly review which services are linked to your account.
- Avoid using SSO for services that handle sensitive information unless you're confident in their security.
