如果有人尝试登录某个账号,但连续四次从一个 IP 地址输入正确的凭据,Looker 会自动锁定用户账号 5 分钟。如果账户被锁定,在五分钟锁定期到期之前,即使拥有正确的凭证,也无法从同一 IP 地址登录。锁定是基于每个用户凭据和 IP 地址进行的,因此,锁定在 IP 地址的用户凭据仍然可以尝试从其他 IP 地址登录,或者其他用户凭据可以尝试从该 IP 地址登录。

If an account is locked, that account is not allowed to login from that same IP address, even with the proper credentials, until the five-minute lockout period expires. Lockouts occur on a per-user credential and per-IP address basis, so a user credential that is locked out on an IP address can still attempt to log in from a different IP address, or a different user credential can attempt to log in from that same IP address.\n\u003e The lockout policy does not apply to [signed embed](/looker/docs/single-sign-on-embedding) users.\n\nThe **Login Lockouts** page in the **Users** section of the **Admin** menu shows a list of user credentials that are currently locked out because their owners exceeded the maximum number of failed login attempts.\n\nIncluded information\n--------------------\n\nUnlocking an account\n--------------------\n\nLooker admins can unlock an account that is currently locked, letting that user attempt to log in again before the five-minute lockout period expires.

Click **Unlock** on the dialog box to unlock the user account.\n\nIf there is a user account associated with the credentials used for the login attempts, the dialog box includes a link to that user account page."]]
