What is the advantage and disadvantage of single sign on SSO?

Single Sign On (SSO) Advantages and Disadvantages

Advantages	Disadvantages
Streamlines user access to their applications	Using a single password increases the chances of password vulnerability
Reduces the load of memorising several passwords	When SSO fails, access to all related systems is lost

What are the benefits of using a single sign on SSO authentication service?

Security and compliance benefits of SSO SSO reduces the number of attack surfaces because users only log in once each day and only use one set of credentials. Reducing login to one set of credentials improves enterprise security. When employees have to use separate passwords for each app, they usually don’t.

Which of the following is the disadvantage of single sign on?

Disadvantages of SSO include the following: It does not address certain levels of security each application sign-on may need. If availability is lost, then users are locked out of the multiple systems connected to the SSO. If unauthorized users gain access, then they could gain access to more than one application.

What is the disadvantage of OTP?

Once sent out, an SMS OTP traverses multiple hops across carriers. It becomes susceptible to delays caused by network congestion. 2FA OTPs being time sensitive (typically three to five minutes), OTP delays can lead to ‘session timeouts’. Operator service outages and gateway downtime also affect SMS-based OTPs.

How does SSO work in mobile app?

Usually, an SSO workflow is initiated at the start of a login sequence. In this use case, the client and the server are built to handle the basic authentication sequence (User –> launches app –> enters credentials –> credentials verified by the server –> user issued a token or cookie allowing access to the app).

What are the risks of single sign-on?

What are the Security Risks in SSO?

• Instant Access to More Than Just the Endpoint. Logon credentials are a major focus for external attackers (81\% of data breaches involve credential misuse).
• Less-Than-Perfect Control over Access Once Granted.
• Little-to-No Adherence to the Principle of Least Privilege.

Is SSO more secure than MFA?

MFA and SSO are both coming at the issue of security and authentication from different areas. SSO is more convenient for users but has higher inherent security risks. MFA is more secure but less convenient. Granting continued access to authenticated users throughout their workday.

What are disadvantages of SAML?

Cons of SAML SSO

• Complex XML-based schema and specification.
• Limited to websites and web applications.
• Lack of user identity data transfer and storage consent.
