Answer 1

You can generate a link with param attached to it. This param can be a timestamp or token.

1. Approach with timestamp

Your page link in email would be something like

<a href="https://your-site/your-page?expires=1600881883">Click here</a>

On your page, you can get the expire timestamp from URL, generate timestamp of current time & compare if 10 min has passed. Show the page if 10 min hasn't passed else do not show it.

Drawback : geek could manipulate the timestamp to have access of expired page as well.

2. Approach with token

• Create a token and maintain it in a separate database table.(eg: Token, page_link, expiry_timestamp).
• Pass this token with the email like

<a href="https://your-site/your-page?token={token_string}">Click here</a>

• On your page, you can get the token from URL, search this token in your table, compare if 10 min has passed. Show the page if 10 min hasn't passed else do not show it.
• This option would be more secure than first approach.

Hope it was helpful.

Thanks

If you are saving data in the database than save current time and then compare that time and date.

if you are not saving it then pass date and time in parameters and compare it with current time date.

Happy coding

I can suggest a solution using cache lifetime (10 minutes), save your token_key into cache service with 10 minutes is cache lifetime, if you can't get your token_key on the cache system, that means the token_key is expired.

Unorthodox solution just for fun :) You mentioned that you're sending inside controller:

namespace MyCompany\MyModule\Controller\Token;

use Magento\Framework\App\Action\Context;
use Magento\Framework\Cache\FrontendInterface;
use Magento\Framework\Controller\Result\Raw;
use Magento\Framework\Controller\ResultFactory;

class Send extends \Magento\Framework\App\Action\Action
{
    /**
     * @var FrontendInterface
     */
    private $cache;

    public function __construct(
        FrontendInterface $cache,
        Context $context
    ) {
        $this->cache = $cache;
        parent::__construct($context);
    }

    public function execute()
    {
        // random_bytes is available at PHP 7
        $token = base64_encode(random_bytes(32));
        $this->cache->save(
            "this is a valid link :)", // value doesn't matter
            "my-token-$token", // key
            ['expiration-token'], // tags
            10*60 // expiration in seconds
        );

        $link = $this->_url->getUrl('myroute/token/verify', ['_query' => ['id' => $token]]);
        // send email with this link to xyz.com/router/controller/action/?id=QWEQ12321

        /** @var Raw $result */
        $result = $this->resultFactory->create(ResultFactory::TYPE_RAW);
        $result->setContents("<a href='$link' target='_blank'>$token</a>");
        return $result;
    }
}

Verify controller:

namespace MyCompany\MyModule\Controller\Token;

use Magento\Framework\App\Action\Context;
use Magento\Framework\Cache\FrontendInterface;
use Magento\Framework\Controller\Result\Raw;
use Magento\Framework\Controller\ResultFactory;

class Verify extends \Magento\Framework\App\Action\Action
{
    /**
     * @var FrontendInterface
     */
    private $cache;

    public function __construct(
        FrontendInterface $cache,
        Context $context
    ) {
        $this->cache = $cache;
        parent::__construct($context);
    }

    public function execute()
    {
        /** @var Raw $result */
        $result = $this->resultFactory->create(ResultFactory::TYPE_RAW);

        $token = $this->_request->getParam('id');
        $isValid = $this->cache->load("my-token-$token");
        if (false === $isValid) {
            $result->setContents('This link does not have power here 😕.');
            return $result;
        }

        // verified, put your code here
        $result->setContents('Valid 👍!');
        return $result;
    }
}
