Change expiration time of password reset link

Answer 1

From admin panel, it doesn't allow user to add a number less than 1, for example if someone wants to add time in minutes. This was the file from where it comes from

/var/www/html/projectName/vendor/magento/module-customer/etc/adminhtml/system.xml

<field id="reset_link_expiration_period" translate="label comment" type="text" sortOrder="60" showInDefault="1" showInWebsite="0" showInStore="0" canRestore="1">
                    <label>Recovery Link Expiration Period (hours)</label>
                    <comment>Please enter a number 1 or greater in this field.</comment>
                    <validate>required-entry validate-digits validate-digits-range digits-range-1-</validate>
                    <backend_model>Magento\Customer\Model\Config\Backend\Password\Link\Expirationperiod</backend_model>
                </field>

As you can see, it has

<validate>required-entry validate-digits validate-digits-range digits-range-1-</validate>

which validate the field, to not to accept number less than one. To achieve this, first you need to override this system.xml file by How to override system.xml core file in magento2

and update validate by this

                <validate>required-entry validate-digits</validate>

Hope it helps.

Answer 2

I have chosen to override function which save config value Create a Folder Customer Path : App/code/Desiredname/Customer create folders etc,i18n,Model and file registration.php

Path/etc/module.xml

    <?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Desiredname_Customer" setup_version="1.1.6">
        <sequence>
            <module name="Magento_Customer"/>
        </sequence>
    </module>
</config>

Path/app/etc/adminhtml/system.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
    <system>
<group id="password" translate="label" type="text" sortOrder="30" showInDefault="1" showInWebsite="1" showInStore="1">

            <field id="reset_link_expiration_period" translate="label comment" type="text" sortOrder="60" showInDefault="1" showInWebsite="0" showInStore="0" canRestore="1">
                <label>Recovery Link Expiration Period (hours)</label>
                <comment>Please enter a number 1 or greater in this field.</comment>
                <validate>required-entry validate-greater-than-zero</validate>
                <backend_model>Desiredname\Customer\Plugin\Model\Config\Backend\Password\Link\Expirationperiod</backend_model>
            </field>
            </group>
   </system>
</config>

This two lines are important

<validate>required-entry validate-greater-than-zero</validate>
                <backend_model>Desiredname\Customer\Plugin\Model\Config\Backend\Password\Link\Expirationperiod</backend_model>

Path\Plugin\Model\Config\Backend\Password\Link\Expirationperiod

Above will allow to insert value in decimals but while saving there is PHP validation to check decimal values and value below 1. Hence had to override this functionality

<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace Desiredname\Customer\Plugin\Model\Config\Backend\Password\Link;

/**
 * Customer Reset Password Link Expiration period backend model
 *
 * @author     Magento Core Team <[email protected]>
 */


class Expirationperiod extends \Magento\Framework\App\Config\Value
{
    /**
     * Validate expiration period value before saving
     *
     * @return $this
     */
     public function beforeSave()
    {
        parent::beforeSave();
        $resetPasswordLinkExpirationPeriod = (float)$this->getValue();
        $this->setValue((string)$resetPasswordLinkExpirationPeriod);
        return $this;
    }
}

To change Label at admin level

Path/i18n/en_US.csv

"Please enter a number 1 or greater in this field.","Please enter a number 0 or greater in this field."
