Comparison between authentication modes

There are some factors that should be taken into account when choosing an authentication mode: Do I need to synchronize users with a directory service to use? Does this authentication mode work with Single Sign-On? What is the level of security and configuration complexity?

By making a comparison between the authentication modes, we have the following relationship:

Authentication mode	Depends on integration with a directory service	Supports Single Sign-On mode	Authentication protocol security level	Level of complexity in the configuration and installation	Recommended for external authentication
Internal	NO	NO	LOW	LOW	NO
NTLM v2	YES	NO	MEDIUM	MEDIUM	NO
LDAP	YES	NO	LOW	MEDIUM	NO
SAML 2.0	YES	YES	HIGH	HIGH	YES
OpenID Connect	NO	YES	HIGH	MEDIUM	YES

IMPORTANT!

SoftExpert recommends the use of SAML 2.0 authentication mode because it is the safest protocol and is widely used by cloud solutions.
