A vCenter Single Sign-On lockout policy specifies the conditions under which a user's vCenter Single Sign-On account is locked when the user attempts to log in with incorrect credentials. You can edit the lockout policy.

About this task

If a user logs in to vsphere.local multiple times with the wrong password, the user is locked out. The lockout policy allows you to specify the maximum number of failed login attempts and how much time can elapse between failures. The policy also specifies how much time must elapse before the account is automatically unlocked.
