# Authentication methods

The Empirica Healthcare Analysis software requires users to authenticate by logging in with a unique user name and password. You can use the following authentication methods:

- Local—User information stored in Empirica Healthcare is used for authentication.
- Single Sign-On (SSO)—User information stored in Oracle® Access Manager is used for authentication.

With local authentication, the Empirica Healthcare Analysis software captures successful and failed login attempts in the User Activity Audit Trail, described in Auditing.

When a user exceeds the allowable number of login attempts that you set in your password requirements, the Empirica Healthcare Analysis software sends an email notification about the account lockout to the site administrator.
