user_activation_keyis one of those keys that WordPress uses for authenticity of a Reset Passwordrequest.
user_activation_key是 WordPress 用于验证重置密码请求真实性的密钥之一。
So, when you are saying this key is empty for some users, the reason is, those users have never requested for a password reset.
因此，当您说某些用户的此密钥为空时，原因是这些用户从未请求过密码重置。
When a password reset is requested a temporary key is generated called check_password_reset_keyand sent via email for the reset process.
当请求重置密码时，会生成一个临时密钥，调用check_password_reset_key并通过电子邮件发送以用于重置过程。
When the user goes to the generated link, this key is directly compared with user_activation_key. If both keys don't match then it is considered to be an Invalid Request. Otherwise it proceeds and the user will be allowed to enter a new password for his account.
当用户转到生成的链接时，此键直接与 进行比较user_activation_key。如果两个键不匹配，则将其视为无效请求。否则，它会继续，用户将被允许为其帐户输入新密码。
If you want to understand how it works with more details, you can check the wordpress documentation.
