@dveeden is this more correct?:
Suggested change
| - This variable sets the authentication method the server advertises during connection establishment. | |
| - This variable sets the default authentication method for users connecting to TiDB. | |
| - Changes to this variable will only affect new users. To modify the authentication plugin of an existing user, use the [`ALTER USER`](/sql-statements/sql-statement-alter-user.md) statement. |

No that's not correct.
This sets the authentication method that is advertised in the server greeting. This may or may not be used by clients to then send a 'login' packet with that authentication method.
The MySQL 8.0 client by default ignores this and uses caching_sha2_password unless there is a explicit method set in the client (unlikely). See https://bugs.mysql.com/bug.php?id=93044 for details.
If the authentication method send by the client matches that of the actual useraccount (mysql.user.plugin) then the authentication will proceed and if not the server send an AuthSwitchRequest to the client with info on what plugin should be used for that specific account.
In MySQL 8.0 this variable also influences the plugin that is used for CREATE USER if no plugin is specified. That's not the case in TiDB.

OK thanks for clarifying. Lets disregard my comment, it LGTM.

In this table, several methods are not supported. And "TLS authentication" has no value.
