Change the user password reset link timeout in Drupal 8 & 9

For Drupal 7: In your settings.php try adding this:

$conf['user_password_reset_timeout'] = '259200';

In Drupal 8, you need to add the following line to your settings.php file:

$config['user.settings']['password_reset_timeout'] = 259200;

One can do the same in Drupal 8 via Drush too.

To get the current setting by default it is 86400 sec means 1 day

drush config:get user.settings password_reset_timeout

To change the reset timeout duration for 2 weeks

drush config:set user.settings password_reset_timeout 1209600
