Signing in to a service

Sign-up with another account

Sign-up with another account

Description

Allowing users to sign-up to a new service, through a service where they already have an account.

For example, the user can sign-up with their Google account to create a new account in a calendar app. In this scenario Google would be referred to as a single sign-on provider.

Advantages

  • Users can access a service without needing to remember another password
  • It’s a fast way to gain access to a new service
  • It can be more secure, as single sign-on providers tend to have more security resources to protect accounts
  • Users only need to trust the single sign-on provider with data about them

Limitations

  • Gaining access may be more difficult if the user isn’t able to access the other service
  • If the account with the single sign-on provider is compromised, the security of linked services is at risk
  • The user might not always be aware how the two services might be sharing data
