Edit the vCenter Single Sign-On Lockout Policy
A vCenter Single Sign-On lockout policy specifies when a user's vCenter Single Sign-On account is
locked if the user attempts to log in with incorrect credentials. Administrators can edit the lockout policy.
If a user logs in to vsphere.local multiple times with the wrong password, the user is locked out. The
lockout policy allows administrators to specify the maximum number of failed login attempts, and set the
time interval between failures. The policy also specifies how much time must elapse before the account is
automatically unlocked.
Note The lockout policy applies only to user accounts, not to system accounts such as
administrator@vsphere.local.
