[Configure link based authentication on the ServiceNow instance. The configured link can be shared with the user through Email or SMS and user can use those links to login to instance.](https://servicenow-prod.fluidtopics.net/cZ5FnD805PF0c6uSjHAVoQ "Support time limited authentication for your ServiceNow instance.") | [Multi-factor authentication (MFA)](https://servicenow-prod.fluidtopics.net/L~LHSAqdromxkWga5GC2IQ "Learn how to activate, use, and configure Multi-factor authentication (MFA).")

[Unique PEM encoded certificates mapped to users instead of user name and password for certificate based authentication.](https://servicenow-prod.fluidtopics.net/WewfzmTkCaaejJWUVqnk4g "Certificate-based authentication lets you mutually authenticate user logins or inbound API requests using certificates from a trusted Certificate Authority (CA).") | [Digest token authentication](https://servicenow-prod.fluidtopics.net/UWAsq9OLuU7opWTpAiK6Yg "The digest token authentication passes user credentials and a digest token within an unencrypted HTTP header.") [Username and the secret in the table, perform an hash operation that is user-specific such as SHA1, SHA 256, or MD5.

User credentials are matched to different saved credentials for each method. Hinweis: * The Okta SSO plugin is deprecated. * To learn more about the security properties that affect authorization processing, see [Access control](https://servicenow-prod.fluidtopics.net/xAmazkRh5FKyeb7q4TQGWw "The access control category audits the process of protecting resources from unauthorized access through granting and denying requests based on a permission model. This includes ensuring an entity accessing a resource holds valid credentials to do so, creating and protecting a well-defined set of roles or permissions and ensuring role or permission controls are protected from replay and tampering.") in Instance Security Hardening Settings. * You can use SAML and Digest Authentication through the Multiple Provider SSO application. {#c_Authentication__ul_wjf_jxj_4tb}
