What is a significant security advantage of using Single Sign-On (SSO)?

1. Increased password complexity

2. Reduced number of password entries required

3. Elimination of all authentication requirements

4. Enhanced network traffic encryption

The correct answer is: Reduced number of password entries required

Using Single Sign-On (SSO) significantly reduces the number of password entries required by allowing users to log in once and gain access to multiple applications and services without needing to enter their credentials again for each one. This convenience not only enhances the user experience by streamlining access but also helps reduce the likelihood of password fatigue, where users might resort to weaker passwords or reuse them across different platforms due to the burden of remembering numerous credentials. By minimizing the number of times users must log in, SSO can also mitigate the opportunity for phishing attacks, as users are not frequently prompted to enter their passwords on various sites. This centralized approach means that, while security still needs to be carefully managed, the overall complexity of managing passwords is lessened for users, potentially leading to stronger security practices. Other choices do not accurately reflect the advantages of SSO; for instance, increasing password complexity is a separate security measure and not inherently linked to SSO's function. Elimination of all authentication requirements is not achievable as some authentication process is always necessary for security purposes. Enhanced network traffic encryption, while important for securing data in transit, is not a direct benefit of implementing SSO itself.
