Comment:

 Replying to [ticket:64785 regnalf]:
 > While there is a filter for the entire form HTML (the_password_form),
 changing only the redirect URL requires brittle string manipulation (like
 str_replace or regex) on the rendered HTML block.

 Not quite, as now with the HTML Tag Processor it is safe and pretty
 trivial to update hidden input:

 {{{#!php
 <?php
 add_filter(
         'the_password_form',
         static function ( string $output, WP_Post $post ): string {
                 $processor = new WP_HTML_Tag_Processor( $output );
                 while ( $processor->next_tag( 'INPUT' ) ) {
                         if (
                                 $processor->get_attribute( 'type' ) ===
 'hidden' &&
                                 $processor->get_attribute( 'name' ) ===
 'redirect_to'
                         ) {
                                 $processor->set_attribute( 'value',
 my_plugin_get_password_redirect_url( $post ) );
                                 break;
                         }
                 }
                 return $processor->get_updated_html();
         },
         10,
         2
 );
 }}}
