Have you ever wondered how some platforms will only have you log in once for all of your various needs, even though they might be different applications, websites, or services? This is essentially what single sign-on is, and it’s quite common in the technology world today. What is single sign-on exactly, and what kind of security does it actually provide for organizations that use it?

Passwords have been a primary data security measure since 1960, when MIT researcher Fernando Corbató suggested the practice—although even he is reportedly slow to take full credit. Why? Well, if you ask Corbató (and his contemporaries, who were the first to implement passwords as we’d recognize them today), the security concerns were limited.

So, have we reached the point where it would be best to replace passwords as the default authentication measure?
