为您的在线帐户启用双因素身份验证后，您可以放心，因为没有其他人可以访问您的帐户。为您的帐户配置此机制时，您还应该为双重身份验证配置备份和恢复选项。^{(backup and recovery options)}

这样，如果您被锁定在您的帐户之外并且无法访问您的双因素身份验证代码^{(authentication code)}生成器，您可以使用您的备份选项^{(backup option)}来访问您的帐户。

在本指南中，我们将向您展示如何为您的Google、Microsoft、Apple、Facebook和LastPass帐户设置双重身份验证的恢复和备份选项。^{(recovery and backup options)}

在 Google 上为双重身份验证设置恢复和备份选项^{(Set Up Recovery and Backup Options for Two-Factor Authentication on Google)}

How To Properly Setup Recovery and Backup Options for Two-Factor Authentication

With two-factor authentication enabled for your online accounts, you have peace of mind knowing that nobody else can access your accounts. When you configure this mechanism for your accounts, you should also configure the backup and recovery options for two-factor authentication.

That way, if you ever get locked out of your accounts and don’t have access to your two-factor authentication code generators, you can use your backup option to access your account.

In this guide, we’ll show you how to set up recovery and backup options for two-factor authentication on your Google, Microsoft, Apple, Facebook, and LastPass accounts.

Set Up Recovery and Backup Options for Two-Factor Authentication on Google

In your Google account, you can add a secondary email address or a phone number that acts as a backup option for two-factor authentication. If you ever get locked out of your account, you can use one of these options to regain access to the account.

For two-factor authentication, you can generate and save backup codes to your computer. This way, you can access your account even if you can’t obtain a code yourself.

To add a secondary email address or phone number to your Google account:

1. Open a web browser on your computer and access the Google Account site.
2. Select Security from the left sidebar and choose Recovery email on the right pane. Select the Recovery phone option instead if you want to add a recovery phone number.
