请问这是什么问题
这个错误提示说明在连接到主服务器时遇到了身份验证问题。具体来说，这是因为在MySQL 8.0版本及以上，使用了新的默认身份验证插件"caching_sha2_password"，而该插件要求使用安全连接（Secure Connection）才能进行身份验证。
为了解决这个问题，你需要在从服务器上使用SSL/TLS等安全连接方式连接到主服务器，或者修改主服务器上的MySQL配置文件，将默认的身份验证插件改为旧版的插件，例如"mysql_native_password"。具体步骤如下：
change master to master_host='192.168.32.129',master_port=3307,master_user='xiaoming',master_password='Root@123456',master_log_file='mysql-bin.000001',master_log_pos=702,require ssl;
[mysqld]
default_authentication_plugin=mysql_native_password
修改完成后，重启MySQL服务使配置生效。
需要注意的是，修改主服务器上的MySQL配置文件可能会影响其他应用程序的正常使用，因此需要谨慎操作。如果不确定如何修改，请咨询数据库管理员或MySQL官方文档。
MySQL 主从同步是一种数据库架构的设计，通过复制主库的数据和DDL操作，从库可以保持与主库数据一致的状态。但是，在使用 MySQL 主从同步时，有时会遇到报错的情况，这会影响到数据库的正常运行。
其中一个常见的报错是“Error 1062: Duplicate entry”，这通常是由于从库上已经存在主库上已经存在的记录，从而导致主从同步失败。如下所示：
