Hi, after minor upgrade 8.0.33-25.1 to 8.0.34-26.1 my error.log flooded with wanings:  
`2023-11-06T09:47:08.461867-00:00 845 [Warning] [MY-013360] [Server] Plugin mysql_native_password reported: ''mysql_native_password' is deprecated and will be removed in a future release. Please use caching_sha2_password instead'`

I adeded to config file:

```auto
# nano /etc/mysql/mysql.conf.d/mysqld.cnf
set global log_error_suppression_list='MY-013360';
authentication-policy = 'caching_sha2_password'

```

After reboot, on server startup i still got error:  
`2023-11-07T08:59:30.230134-00:00 0 [Warning] [MY-010918] [Server] 'default_authentication_plugin' is deprecated and will be removed in a future release. Please use authentication_policy instead.`

```auto
select @@default_authentication_plugin, @@authentication_policy;
+---------------------------------+-------------------------+
| @@default_authentication_plugin | @@authentication_policy |
+---------------------------------+-------------------------+
| mysql_native_password | caching_sha2_password |
+---------------------------------+-------------------------+

```

But i did not set this parameter and it is not in my mysqld.cnf (default for 8.0 should be `caching_sha2_password`), so I set in mysqld.cnf :  
`default-authentication-plugin = 'caching_sha2_password'`

Reboot once more. Now I have:

```auto
 SQL > select @@default_authentication_plugin, @@authentication_policy;
+---------------------------------+-------------------------+
| @@default_authentication_plugin | @@authentication_policy |
+---------------------------------+-------------------------+
| caching_sha2_password | caching_sha2_password |
+---------------------------------+-------------------------+

```

But errors still flooding my error.log file 2-3 warnings every second when for testing I set back supressing:  
`set global log_error_suppression_list=''; `

2023-11-06T09:47:08.461867-00:00 845 [Warning] [MY-013360] [Server] Plugin mysql\_native\_password reported: ‘‘mysql\_native\_password’ is deprecated and will be removed in a future release. Please use caching\_sha2\_password instead’`

Did this mean that I must recreate all my users accounts on Server?  
`ALTER USER 'dev-user'@'%' IDENTIFIED WITH caching_sha2_password BY 'xxxxxxxxxxxxxxxx';`

There is a lot of users on a lot of clusters.  
Is there any posibility to avoid this transfer from `mysql_native_password` to `caching_sha2_password`?
