namecheap 域名服务商,每次登录都需要验证码

A trusted device is not just a machine or gadget you use. It consists of multiple parameters that help to identify you as a legit account owner.
The following actions may trigger sending a confirmation code email:

Logging in with another browser;
Finishing the previous session by signing out of your account;
Using the password reset option;
Logging in from another location;
Making a browser data cleanup;
Logging into the Namecheap VPN application.

If you would like to disable Trusted Device verification for your account, I suggest you enabling any 2FA method.


翻译后:

可信设备不仅仅是您使用的机器或小工具。它由多个参数组成，有助于将您标识为合法帐户所有者。

以下操作可能会触发发送确认码电子邮件：

使用其他浏览器登录；

通过注销帐户完成上一个会话；

使用密码重置选项；

从其他位置登录；

进行浏览器数据清理；

登录namesheap VPN应用程序。



如果您想为您的帐户禁用可信设备验证，我建议您启用任何2FA方法。

因为我是直接退出账号的,所有下次登录还要验证码,并且不能清空涉及到这个网站的缓存.

Two-Factor Authentication (2FA) adds an extra layer of security to your Namecheap account in addition to your username and password by requiring access to the phone number associated with your account. When Two-Factor Authentication is enabled, your account cannot be accessed by anyone unauthorized by you, even if they have stolen your password.
