How to Fix: Admin Cannot Login in Magento 2

Experiencing Login Issues with Magento 2 Admin

After updating your Magento store to the latest version and completing essential setup tasks, such as meeting server requirements, implementing SSL, configuring your Website, Store, and Store View, and providing details in the store configuration, you suddenly faced an issue where Magento 2 could no longer be logged into the admin panel.

Even after conducting thorough checks, there are no error messages or console issues in Chrome/Firefox. Clearing sessions and cache did not resolve the problem either. Despite finding answers that consistently point to sessions and cache settings, following the documentation did not resolve the issue.

The Solution for Login Issues

If the issue of being unable to log in to the Magento 2 admin persists, it’s possible that another problem is arising from domain cookies. Often, instructions recommend setting the cookie domain as domain.com, assuming it’s a subdomain. However, if the store’s base URL is registered as http://domain.com, a conflict may arise at this point.

There are two ways to address this issue.

Solution 1: If you do not plan to use a subdomain for cookie storage

Navigate to Stores -> Configuration -> Web -> Cookie Domain, and set it as “domain.com” without a preceding period and parentheses.

Solution 2: If you are planning for a future that involves setting cookie storage

For the first solution, set the Cookie Domain as “.domain.com” with a preceding period and without parentheses. Then, in the base URL configuration under Stores -> Configuration -> Web -> Base URL, append “www” to your domain name, like http://www.domain.com. If SSL is implemented (which is recommended), ensure the secure base URL includes “https” as part of the setup.
