FirebirdClient = 10.3.2
error: Not supported plugin 'Legacy_Auth'.

à FirebirdSql.Data.Client.Managed.AuthBlock.Start(Byte[] serverData,
String acceptPluginName, Boolean isAuthenticated, Byte[] serverKeys)
à FirebirdSql.Data.Client.Managed.GdsConnection.Identify(String
database)
à
FirebirdSql.Data.Client.ClientFactory.CreateManagedDatabase(ConnectionString
options)
à
FirebirdSql.Data.Client.ClientFactory.CreateDatabase(ConnectionString
options)
à FirebirdSql.Data.FirebirdClient.FbConnectionInternal.Connect()
à FirebirdSql.Data.FirebirdClient.FbConnection.Open()

With the same connection line :
with EntityFrameworkCore it's ok.
without EntityFrameworkCore it's error: Not supported plugin
'Legacy_Auth'.

Any ideas?

EF Core has absolutely zero impact on auth - the connection string is just passed to FirebirdClient. Hence there's probably some other difference. But either way, without a repro it is difficult to troubleshoot.

OK, found the error.
if you're using a .ini configuration file, if the last line is the
connection line and ... it ends with a comma (typically copy/paste from
a json) you get this kind of error :-(
3 hours for this!
