To access Opsview Monitor's web user interface, you need to login to the system

A user logs in based on their username and password combination stored in the configuration database. You can configure Opsview to use [LDAP or Active Directory](🔗) if you prefer.

For security, Opsview Monitor will block an IP address that has more than 50 failed login attempts within an hour, or block login by a user that has more than 10 failed login attempts in the last hour. These values can be configured in the [Web App](🔗)

then you have already hit the maximum sessions you are allowed to have, as configured by your system administrator (default: 10). This session limit covers both the UI and the REST API sessions combined.
