The LastPass SSO solution leverages SAML 2.0 to provide the best performance in endpoint security solution for a wide range of business needs. Because of its functionality, versatility, reliability, and scalability, SAML is an ideal option for service providers and identity providers alike.

LastPass provides a true SSO experience for end users, allowing them to access key apps without having to enter a unique password, thus delivering a more efficient authentication flow and enhanced productivity.

In this article we will outline setting up LastPass as a SAML Identity Provider so that we can utilize Telnyx's Single Sign-On feature. LastPass is a password manager that stores encrypted passwords online. It is one of the many SAML providers that Telnyx supports for our SSO feature.
